Pearl ash' is

Options

A. `K_(2)CO_(3)`
B. `KMnO_(4)`
C. `K_(2)O_(3)`
D. KOH

Answer

**Step-by-Step Solution:**

1. **Identify the Chemical Composition**: Pearl ash is chemically represented as K2CO3. This means it is a compound made up of potassium (K) and carbonate (CO3).

2. **Color and Appearance**: Pearl ash is described as being white in color. This characteristic is important for its identification.

3. **Solubility in Water**: K2CO3 is highly soluble in water. This property is significant as it affects how pearl ash behaves in different environments, particularly in aqueous solutions.

4. **Deliquescent Nature**: Due to its high solubility, K2CO3 has a deliquescent nature, meaning it can absorb moisture from the atmosphere. This results in the compound absorbing water and potentially forming a solution if enough moisture is present.

5. **Conclusion**: Therefore, pearl ash is essentially potassium carbonate (K2CO3), which is a white, highly soluble, and deliquescent compound.
