Acid–Base Titration

Ammonia Titration Curve with HCl

Description

Ammonia titration with hydrochloric acid shows how a weak base behaves as acid is added. The curve is the mirror image of a weak acid titrated with a strong base. In this case, ammonia acts as the weak base, and hydrochloric acid acts as the strong acid.

The starting pH of 50 mL of 0.1 M ammonia ...

Transcript

The weak base versus strong acid titration curve is the reverse of a weak acid-strong base titration curve.

Aqueous ammonia forms ammonium and hydroxide ions. As calculated from the ICE table and Kb expression, the initial pH of 50 mL of 0.1 M ammonia solution is basic with an 11.11 pH.

On adding 25 mL of 0.1 M ...
