Which of the following is the strongest base

Options

A. `Be(OH)_(2)`
B. `Mg(OH)_(2)`
C. `Al(OH)_(3)`
D. `Si(OH)_(4)`

Explanation

To determine which of the given compounds is the strongest base, we will analyze each option based on their properties.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- The options provided are:
1. Beryllium Hydroxide (Be(OH)2)
2. Magnesium Hydroxide (Mg(OH)2)
3. Aluminum Hydroxide (Al(OH)3)
4. Silicon Hydroxide (Si(OH)4)

2. **Analyze Beryllium Hydroxide (Be(OH)2)**:
- Beryllium hydroxide is amphoteric, meaning it can act as both an acid and a base. However, it is not considered a strong base.

3. **Analyze Magnesium Hydroxide (Mg(OH)2)**:
- Magnesium hydroxide is a strong base. It dissociates in water to produce hydroxide ions (OH⁻), which contribute to its basicity.

4. **Analyze Aluminum Hydroxide (Al(OH)3)**:
- Aluminum hydroxide is also amphoteric. It can act as both an acid and a base, but it is generally weaker as a base compared to magnesium hydroxide.

5. **Analyze Silicon Hydroxide (Si(OH)4)**:
- Silicon hydroxide is a weak acid. It does not exhibit strong basic properties.

6. **Compare the Bases**:
- Among the compounds analyzed, magnesium hydroxide (Mg(OH)2) stands out as the strongest base due to its ability to fully dissociate in solution and produce a significant concentration of hydroxide ions.

### Conclusion:
The strongest base among the given options is **Magnesium Hydroxide (Mg(OH)2)**.
