Solution: Classify K2Oa. neutral saltb. acidic saltc. basic salt

Problem

Classify K2O

a. neutral salt

b. acidic salt

c. basic salt

Solution

We’re being asked to classify K2O if it is a basic or acidic salt


The acidic ions are usually cations and include:

1. Transition metals with a charge of +2 or higher. Transition metals not satisfying this condition are neutral.

2. Main group metals with a charge of +3 or higher. Main group metals not satisfying this condition are neutral.

3. Amines, which are compounds that contain only N and H (i.e. NH­3) or C, N, and H (i.e. CH3NH2)
