Answer :
Final answer:
To calculate the pH at different volumes of base, determine the concentration of acetic acid and acetate ion and use the ionization equation.
Explanation:
The pH of a solution can be determined by calculating the concentration of hydronium ions (H3O+). In this case, as acetic acid is a weak acid, it undergoes a partial ionization in water. The equation for the ionization reaction is:
CH3COOH(aq) <==> H+(aq) + CH3COO-(aq)
Using the provided values of the sample size and concentration of acetic acid, you can calculate the initial concentration of the acid.
When calculating the pH after each volume of base has been added, you will need to consider the reaction between the acid and base. This will help determine the concentration of remaining acetic acid and the concentration of the acetate ion. From these concentrations, you can calculate the concentration of hydronium ions and therefore the pH of the solution.
