(a)

Interpretation Introduction

Interpretation:

After addition of $\text{3}\text{.0 mL}\text{of}\text{1}\text{.0 M KOH}$ in the titration of $\text{25}\text{.0 mL of 0}\text{.125 M}\text{HCl}$ with $\text{0}\text{.100 M}\text{KOH}$, $\text{pH}$ of the solution should be calculated.

Concept introduction:

Acid-base neutralization reaction:

The aqueous solution of acid react with aqueous solution of base to produce soluble salt with water in known as acid-base neutralization reaction because of where neutralization is occur.

pH:

$\text{pH}$ is a logarithmic expression to express a solution is acidic, basic or neutral.  The $\text{pH}$ scale has values between 1 and 14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

(b)

Interpretation Introduction

Interpretation:

After addition of $\text{20}\text{.0 mL}\text{of}0.\text{10 M KOH}$ in the titration of $\text{25}\text{.0 mL of 0}\text{.125 M}\text{HCl}$ with $\text{0}\text{.100 M}\text{KOH}$, $\text{pH}$ of the solution should be calculated.

Interpretation Introduction

Interpretation:

After addition of $\text{65}\text{.0 mL}\text{of}\text{1}\text{.0 M KOH}$ in the titration of $\text{25}\text{.0 mL of 0}\text{.125 M}\text{HCl}$ with $\text{0}\text{.100 M}\text{KOH}$, $\text{pH}$ of the solution should be calculated.
