Presence of water is avoided in the preparation of `H_(2)O_(2)` from `Na_(2)O_(2)`. Explain.

Explanation

To understand why the presence of water is avoided in the preparation of hydrogen peroxide (H₂O₂) from sodium peroxide (Na₂O₂), let's break down the process step by step:

### Step 1: Understanding the Reaction
The preparation of hydrogen peroxide from sodium peroxide involves a chemical reaction where sodium peroxide reacts to produce hydrogen peroxide. The general reaction can be represented as:
\[ \text{Na}_2\text{O}_2 + \text{H}_2\text{O} \rightarrow \text{H}_2\text{O}_2 + \text{NaOH} \]

### Step 2: Role of Water
In this reaction, water (H₂O) is a reactant. However, when sodium peroxide comes into contact with water, it reacts vigorously. This reaction leads to the formation of sodium hydroxide (NaOH) alongside hydrogen peroxide.
