The values of `K_(sp)` of two sparingly solubles salts, `Ni(OH)_(2)` and `AgCN` are `2.0 xx 10^(-15)` and `6 xx 10^(-7)` respectively, which salt is more soluble? Explain

Explanation

To determine which of the two sparingly soluble salts, Ni(OH)₂ or AgCN, is more soluble, we can compare their solubility products (Ksp) and calculate the solubility of each salt from their Ksp values.

### Step-by-Step Solution:

1. **Identify the Ksp Values**:
- For Ni(OH)₂, Ksp = 2.0 × 10^(-15)
- For AgCN, Ksp = 6.0 × 10^(-7)
