Interpretation Introduction

(a) Interpretation:

The pH of a 1 M NH₄Cl solution should be calculated.

Concept Introduction:

For a weak acid or a weak base, the dissociation reaction is in equilibrium and the equilibrium constant is known as acid or base dissociation constant. For such a solution, concentration of each species is calculated using ICE table.

The pH of solution is calculated as follows:

pH=−log[H+]

Here, [H+] is concentration of hydrogen ions in the solution.

Interpretation Introduction

(b) Interpretation:

The pH of solution resulting from addition of 10 mL of a 1 M NaOH to 40 mL of 1 M NH₄Cl.

Concept Introduction:

For a buffer solution, pH is calculated using Henderson-Hasselbalch equation as follows:

pH=pKa+log[Conjugate base][acid]

Here, pH is −log[H+] of solution and pKa is -log(Ka) of weak acid.

Interpretation Introduction

(c) Interpretation:

The pH of the solution that results from the addition of 30 mL of 1 M NaOH to 40 mL of 1 M NH₄Cl.
