(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:
Here,
(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:
Here, pH is
(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.
Concept Introduction:
For a buffer solution, pH is calculated using Henderson-Hasselbalch equation as follows:
Here, pH is
