Magnesium oixde when mixed in water and turned red litmus to blue . This shown that magnesium oxide is ____in nature.

Options

A. acdic
B. basic
C. neutral
D. reactive

Answer

To determine the nature of magnesium oxide when mixed with water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Substance**: We start with magnesium oxide (MgO).

2. **Mix with Water**: When magnesium oxide is mixed with water, it reacts to form magnesium hydroxide (Mg(OH)₂).

3. **Observe the Litmus Test**: The problem states that this mixture turns red litmus paper to blue.

4. **Understand Litmus Paper Reaction**: Red litmus paper turning blue indicates that the solution is basic in nature.

5. **Conclude the Nature of Magnesium Oxide**: Since magnesium oxide produces a basic solution (magnesium hydroxide) when mixed with water, we conclude that magnesium oxide itself is basic in nature.

6. **Final Answer**: Therefore, the answer to the question is that magnesium oxide is **basic** in nature.
