Study Notes
Titration of Ammonia
- Ammonia (NH3) reacts with strong acid in water and in acetic acid through two equilibrium reactions:
- H3O+ + NH3 ↔ H2O + NH4+ in water
- CH3COOH2+ + NH3 ↔ CH3COOH + NH4+ in acetic acid
Key Findings
- Ammonia appears more basic in acetic acid than in water
- CH3COOH2+ is a stronger proton donor than H3O+
- This difference in proton-donating ability is responsible for ammonia's increased basicity in acetic acid
