FREE Expert Solution

We’re being asked to determine which ionic compound is not affected by the pH of the solution.


For the solubility of an ionic compound to be not affected by a change in pH, it must contain a neutral ion.

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)


To determine if an anion is a basic ion, we should add H+ to it. 

If the addition of H+ leads to:

1. a weak acid, the anion is basic.
2. a strong acid, the anion is neutral.
