a)
Interpretation: To determine whether
Concept Introduction: Depending on the ability of the ion to react with water the nature of the salt can be determined. If the cation is a strong base and the anion is a strong acid, then the solution or the salt will be neutral. If the cation is a weak base and the anion is a strong acid then the solution will be acidic. If the cation is a strong base and the anion is a weak acid, then the solution will be basic.
