`Be(OH)_(2)` is -

Options

A. Acidic
B. Basic
C. Amphoteric
D. Neutral

Answer

To determine the nature of `Be(OH)₂`, we need to analyze its properties. Here's a step-by-step solution:

### Step 1: Understanding the Compound
`Be(OH)₂` is beryllium hydroxide. It is formed by the reaction of beryllium oxide with water or by the reaction of beryllium with a strong base.

**Hint:** Identify the compound and its components to understand its behavior.

### Step 2: Classifying Hydroxides
Hydroxides can be classified as acidic, basic, amphoteric, or neutral.
- Basic hydroxides are typically formed by alkali metals and alkaline earth metals.
- Acidic hydroxides are usually formed by non-metals.
- Amphoteric hydroxides can react with both acids and bases.

**Hint:** Recall the general classification of hydroxides based on their reactivity.

### Step 3: Beryllium's Position in the Periodic Table
Beryllium is an alkaline earth metal located in Group 2 of the periodic table. Unlike other alkaline earth metals, beryllium has a high ionization energy and a small ionic radius, which influences its chemical behavior.

**Hint:** Consider the properties of beryllium compared to other alkaline earth metals.

### Step 4: Amphoteric Nature of `Be(OH)₂`
Beryllium hydroxide (`Be(OH)₂`) is classified as amphoteric because:
- It can react with acids to form beryllium salts (e.g., reacting with hydrochloric acid to form `BeCl₂`).
- It can also react with strong bases to form beryllate ions (e.g., reacting with sodium hydroxide).

**Hint:** Look for reactions that demonstrate both acidic and basic characteristics.

### Step 5: Conclusion
Based on the above analysis, we conclude that `Be(OH)₂` is amphoteric in nature.

**Final Answer:** `Be(OH)₂` is amphoteric.
