Consider the titration of 40.0 mL of 0.200 M HClO 4 by 0.100 M KOH. Calculate the pH of the resulting solution after the following volumes of KOH have been added. a. 0.0 mL b. 10.0 mL c. 40.0 mL d. 80.0 mL e. 100.0 mL

The titration concentration of KOH , volume and concentration of HClO4 is given. The pH of resulting solution after the addition of KOH is to be calculated for the given volumes of KOH .

Concept introduction:

Titration is a process to determine the concentration of an unknown solution with the help of a solution of a known concentration value.

The pH is calculated using the formula,

pH=−log10[H+]

The relation between pH and pOH is,

pH+pOH=14

To determine the pH of the resulting solution, after the addition of 0.0 mL of KOH .

Explanation of Solution

Explanation

Given

Concentration of HClO4 is 0.200 M .

HClO4 is a strong acid; hence, it completely dissociates into ions. The major species present in the solution are H+,ClO4− and H2O .

The pH is determined by [H+] present in the solution.

Since HClO4 completely dissociates into ions, 0.200 M HClO4 contains 0.200 M H+
