Which of the following salts is the most basic in aqueous solution (1)...
Introduction:
The basicity of a salt is determined by the strength of its conjugate base. A strong conjugate base will readily accept protons and act as a strong base in aqueous solution.
Comparison of salts:
1. CH3COOK:
- The conjugate base of acetic acid is acetate ion (CH3COO-).
- Acetate ion is a weak base as it does not have a strong tendency to accept protons.
- Therefore, CH3COOK is not a strong base in aqueous solution.
2. FeCl3:
- FeCl3 is an ionic compound that dissociates in water to form Fe3+ and Cl- ions.
- Neither Fe3+ nor Cl- are strong bases.
3. Pb(CH3COO)2:
- The conjugate base of acetic acid is acetate ion (CH3COO-).
- Pb2+ is a relatively large cation that can polarize the acetate ion, making it a stronger base.
- Therefore, Pb(CH3COO)2 is a stronger base than CH3COOK.
4. Al(CN)3:
- CN- is a strong conjugate base as it readily accepts protons.
- Therefore, Al(CN)3 is the strongest base among the given salts.
Conclusion:
In summary, Al(CN)3 is the most basic salt in aqueous solution among the given options.
