fruit juice contains an unknown percentage of citric acid. During a titration 33.50 cm³ of 0.0102 M sodium hydroxide is required to neutralise the citric acid in 50.0 cm³ of fruit juice. The unbalanced reaction equation is given in Figure 10. Citric acid is a triprotic acid – it can donate three H⁺ ions in aqueous solution. You can assume that the density of the fruit juice is the same as that of water. What is the percentage of citric acid in the sample? [Round the answer to three decimals. Do not type in the percentage sign. Use a decimal point.] * Your answer

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
