Concept explainers
Interpretation:
The volume of the barium hydroxide
Concept introduction:
Neutralization reactions are the reactions in which the acid or base is neutralizing another base and acid.
The unknown value of any property can be find out using the stoichiometry from the balanced chemical equation.
Answer to Problem 40E
The volume of
Explanation of Solution
Stoichiometry of the reaction comes in and plays a very important role in doing the calculation of measurable quantities. Stoichiometry is nothing but a comparison of quantities of one species with the other on the basis of a balanced chemical equation. The numerical value placed in from of the compounds tells about the number of moles of that compound reacting or producing in the reaction.
The balanced chemical equation of the reaction that happens between the barium hydroxide and potassium hydrogen phthalate is shown below.
Molarity is defined as the number of moles of solute per unit volume in liters of solution.
The formula of molarity in terms of volume in milliliters is given below.
It is multiplied by 1000 to convert the volume in milliliters to liters.
The number of moles of any substance is related to its mass by the formula shown below.
Calculate the number of moles of
The molar mass of
The mass of
Substitute the values of m and M in equation (2).
The number of moles of barium hydroxide
Let us suppose the volume of barium hydroxide
The molarity of the barium hydroxide
Substitute the values of molarity and volume in equation (1).
Rearrange to find out the number of moles as shown below.
Compare the moles of both the
One mole of
Therefore, each one mole of

- What is the molar concentration of an H2SO4 solution if a 50.0-mL sample requires 9.65 mL of a 1.33 M solution of NaOH to reach the equivalence point?arrow_forwardOranges and grapefruits are known as citrus fruits because their acidity comes mainly from citric acid, H3C6H5O7. Calculate the concentration of citric acid in a solution if a 30.00-mL sample is neutralized by 15.10 mL of 0.0100 M KOH. Assume that three acidic hydrogens of each citric acid molecule are neutralized in the reaction.arrow_forwardVitamin C has the formula C6H8O6. Besides being an acid, it is a reducing agent. One method for determining the amount of vitamin C in a sample is to titrate it with a solution of bromine, Br2, an oxidizing agent. C6H8O6(aq) + Br2(aq) 2 HBr(aq) + C6H6O6(aq) A 1.00-g "chewable" vitamin C tablet requires 27.85 ml of 0.102 M Br2 for titration to the equivalence point. What is the mass of vitamin C in the tablet?arrow_forward
- Arsenic acid, H3AsO4, is a poisonous acid that has been used in the treatment of wood to prevent insect damage. Arsenic acid has three acidic protons. Say you take a 25.00-mL sample of arsenic acid and prepare it for titration with NaOH by adding 25.00 mL of water. The complete neutralization of this solution requires the addition of 53.07 mL of 0.6441 M NaOH solution. Write the balanced chemical reaction for the titration, and calculate the molarity of the arsenic acid sample.arrow_forwardThe pungent odor of vinegar is a result of the presence of acetic acid, CH3COOH. Only one hydrogen atom of the CH3COOH reacts with a base in a neutralization reaction. What is the concentration of acetic acid if a 10.00-mL sample is neutralized by 3.32 mL of 0.0100 M strontium hydroxide?arrow_forward
