In the modern industrial era, the levels of Carbon Dioxide produced are much more significant than in years before. Due to Carbon Dioxides involvement in ocean acidification, this is a major issue. Since the beginning of the industrial revolution, the pH of the ocean surface has fallen by 0.1 units. Although this may not seem significant, due to the logarithmic properties of the pH scale, this change signifies about a 30% increase in ocean acidity. If this issue isn’t addressed, there will be dire consequences for both marine organisms, as well as humans. To understand ocean acidification, some chemistry needs to be defined and understood.

The molecules gain a shell of water molecules and are transformed from CO2 (g) to CO2 (aq). This is known as the dissolution process. This can be shown in the equilibrium reaction.
Equilibrium is a state in a reaction in which both the reactants and the products are present in concentrations that are both constant, and will not change over time. This state results when the forward reaction is proceeding at the same rate as the reverse reaction. An example of this can be seen in the dissolution of Sodium Chloride in water. If the equilibrium equation NaCl(s) NaCl (aq) is used, we can see that the compound in the solid form is re-crystalizing at the same rate as the aqueous form is dissolving. There are 3 main disturbances that can alter equilibrium, a change in concentration of reactants or products, a change in temperature or a change in pressure. According to Le Chatelier’s principle, if any of these three is disturbed, the system compensates by shifting the equilibrium to either the left or the right. This can be seen in the equilibrium reactions associated with sea water. In the dissolution process of CO2 discussed before, not all of the CO2 molecules remain dissolved. A small amount react with the water to form carbonic acid (H2CO3), which can be seen in the equation CO2 (aq) + H2O H2CO3 (aq). As carbonic acid is a weak acid, it can dissociate to bicarbonate or carbonate. These two equations respectfully are H2CO3 (aq H+ (aq) + HCO3- (aq),
The Effect of Temperature on the Solubility of Carbon Dioxide in Water under Constant Pressure
The rising carbon dioxide (CO2) from the burning of fossil fuels and other human activities continues to affect our atmosphere, resulting in global warming and climate change. This carbon dioxide is also altering the chemistry of the oceans, causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have drastic consequences on marine ecosystems. Such as altering species composition, disrupting marine food webs and ecosystems and harming fishing, tourism and other human activities connected to the sea.
Over the years Carbon Dioxide has been significantly increasing from human activity. CO2 has a concentration of about 400 ppmv (parts per million volume). Its concentration in the atmosphere was about 280 ppmv before the Industrial Revolution, now it has increased immensely to about 380 ppmv in 2006. Many have said Carbon Dioxide has been the main reason or cause of global warming; saying that if we produce too much of this greenhouse gas it can create a global climate change. Even though carbon dioxide affects the temperature of the atmosphere it also affects the acidity of water specifically in the ocean.

Changes in CO2 are affecting us and our environment in many ways. the most predominant effect of carbon dioxide changes is on the weather and oceans. Unpredictable heat waves are occurring in unforeseen parts of the world (i.e. Europe) and global temperatures as a whole are rising. The rise in the temperatures can not only affect us but the flora and fauna around us. With hotter temperatures, some plants and animals may be unable to adjust which would result in a chain reaction. Heat is affecting the oceans as well and many long standing glaciers or ice shelves to melt and alter the oceans temperature, levels and salinity. These, resultantly, are causing disruptions to the thermohaline conveyor and are effecting islands or seaside town as the water level
Since the beginning of the industrial revolution, mankind has slowly increased the total greenhouse gas emissions that enter the atmosphere. Over time, this pollution began to add up. Now planet Earth is struggling to maintain its health with the combined forces of global warming and ocean acidification looking to bring demise. From all portions of the world, troubling changes are emerging in the chemistry of our oceans’ waters. The oceans takes in around a quarter of the Carbon Dioxide that mankind releases into the atmosphere every year, so as atmospheric Carbon Dioxide levels rise, so do the
Carbon Capture and Sequestration is the process of reducing emissions of carbon dioxide by injecting the compound back in the ground. The process takes 3 steps:
“How acidification threatens ocean from the inside out: Carbon dioxide emissions are making the oceans more acidic, imperiling the growth and reproduction of species from plankton to squid”, by Marah J. Hardt and Carl Safina addresses the dangers of increasing acidity in the ocean caused by carbon dioxide. Hardt, a research scientist and writer, is the founder of Ocean Ink. Safina, an adjunct professor at Stony Brook University, is the founding president of the Blue Ocean Institute.
Over the past couple of years, no other issue has received more attention in the marine community than ocean acidification. Marine biologists have been constantly working towards solving this issue and are hoping to see improvement’s very soon. Ocean acidification refers to the relentless growth in acidity of the Earth’s oceans. This on-going acidity has attributed to an important element; a constant rise of carbon dioxide levels in the Earth. The number one reason this issue is still happening is because of burning fossil fuels. In addition to burning fossil fuels, it has come to a point where it has enlarged a large amount of carbon dioxide by releasing it into the atmosphere. Chemists have taken this issue into attention that carbon enters the ocean and combines with seawater to fallout acid, which boosts the level of acidity. This process is known as ocean acidification.
Sometimes called “climate change’s equivalently destructive twin”, ocean acidification is becoming more and more noticeable as the seawater’s changing chemistry begins to cause environmental and economical problems. When the Industrial Revolution began around 1760, fossil fuel–powered machines gained an immense amount of accessibility and popularity. Since then, carbon dioxide (CO2) levels in the atmosphere have risen enough to change the pH of the world’s oceans. Given that the ocean absorbs almost half of the CO2 that is released into our atmosphere, ocean acidification is inclining into an even greater problem as fossil fuels become a more common energy source in our society. Higher acid levels can harm wildlife, disrupt the food chain, and negatively impact industries that rely on the ocean for business. Ocean acidification is causing growing dilemmas for both marine ecosystems and ocean-based economies. Although many companies and organizations are attempting to fix this problem, acidification is still threatening to cause increasingly harmful issues for the future.
A bottle of soda is full of carbon dioxide. The bubbles stay stuck in the liquid until the bottle is opened. When you drop an item into a bottle of soda, bubbles form on the surface of the object that was dropped in. This Process is called, “nucleation.” Nucleation is the process that happens in the formation of a crystal from a solution, a liquid, or a vapour.
According to Ocean Portal, “in the past 200 years alone, ocean water has become 30 percent more acidic”. The rapid growth of acidity within the oceans is dramatically impacting ecosystems- even the shells of animals are disintegrating in the acid contaminated seawater.
Since the industrial revolution, anthropogenic inputs of carbon dioxide to the atmosphere have increased dramatically. Concentrations in the atmosphere have risen 40% from 1750 to 2011, reaching record highs of 390.5 ppm (Stocker, et al., 2013). Due to this, the amount of dissolved CO2 in the oceans has also increased causing acidification of the oceans which can have several effects, mainly on calcifying organisms. Climate change has also influenced the stratification of the oceans due to density changing affecting nutrient distribution. So far, although a number of methods have been explored, there have been no solutions that don’t have their own issues.
Carbon dioxide is one of the major greenhouse gases, and is one of the most common gases found in the earth’s atmosphere. Carbon dioxide is released into the atmosphere in mass amounts by human activities and then absorbed by our oceans. The main way that carbon dioxide is added to the atmosphere is by the burning of fossil fuels and deforestation. Increased energy composition and with the industrialization age, beginning in the 18th century, has led to a drastic spike in the burning of fossil fuels and therefore the release of carbon dioxide into the atmosphere. The main emitters of carbon dioxide are cars, airplanes, and factories
Ocean acidification is happening throughout the oceans at this very moment. Ever since the start of the Industrial Revolution, excess amounts of carbon dioxide have been released to the atmosphere. The ocean absorbs around a quarter of the carbon dioxide released every year, so as the amount of CO2 increases in the air, so does the amount of CO2 in the ocean. Scientists, at first thought this was beneficial to the environment as the ocean was removing greenhouse gas from the atmosphere; however, it slowly changed the chemistry of the oceans. The increase of carbon dioxide in the oceans led them to become more acidic, which affected the marine ecosystems. The PMEL Carbon Program monitored the oceans for three decades and they recently revealed how carbon dioxide affected the coral reef systems in the North Pacific
