Question

Consider the following salts:
Na2CO3, NaCl, NH4Cl, CH3COONa, K2SO4, (NH4)2SO4
Which of these salts will give:

basic solutions (or alkaline solutions)?

Solution

The salt solutions of CH3COONa and Na2CO3 are basic, because these salts are each formed from a weak acid and a strong base. The ionisation of a weak acid is not complete, whereas a strong base ionises completely. Hence, there are more OH- ions than H+ ions, making the solutions basic.

  Is there an error in this question or solution?
