When epsom salt is heated at `150^@C`, the compound obtained is

Options

A. `MgSO_4`
B. `MgSO_4 . H_2O`
C. `MgSO_4 . 7 H_2O`
D. `MgO`

Explanation

To solve the question regarding the compound obtained when Epsom salt is heated at 150°C, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Epsom Salt**:
- Epsom salt is chemically known as Magnesium Sulfate Heptahydrate, represented as MgSO4·7H2O.

2. **Understand the Heating Process**:
- When Epsom salt is heated, it undergoes a dehydration process where water molecules are lost.

3. **Determine the Temperature**:
- The question specifies heating at 150°C. It’s important to note that different temperatures lead to different products.

4. **Analyze the Dehydration at 150°C**:
- At 150°C, Epsom salt loses 6 out of the 7 water molecules. This results in the formation of Magnesium Sulfate Monohydrate.

5. **Write the Resulting Compound**:
- The compound obtained after heating Epsom salt at 150°C is MgSO4·H2O.

### Final Answer:
The compound obtained when Epsom salt is heated at 150°C is Magnesium Sulfate Monohydrate (MgSO4·H2O).
