Select the basic and acidic radicals in the following compounds
`Mg(OH)_2`

Explanation

To determine the basic and acidic radicals in the compound \( Mg(OH)_2 \), we can follow these steps:

### Step 1: Identify the components of the compound
The compound \( Mg(OH)_2 \) consists of magnesium (Mg) and hydroxide ions (OH).

### Step 2: Determine the charge of the radicals
- **Basic Radical**: Basic radicals are positively charged ions (cations). In this case, magnesium has a charge of \( +2 \) (Mg\(^{2+}\)).
- **Acidic Radical**: Acidic radicals are negatively charged ions (anions). The hydroxide ion has a charge of \( -1 \) (OH\(^{-}\)).
