White phosphorus is stored in

Options

A. ether
B. water
C. alcohol kerosene
D. Oil

Answer

**Step-by-Step Solution:**

1. **Understanding White Phosphorus**: White phosphorus is a highly reactive form of phosphorus. It is known for its low ignition temperature and tendency to ignite spontaneously in air.

2. **Reactivity of White Phosphorus**: Due to its high reactivity, white phosphorus can easily catch fire when exposed to air. This poses a significant risk if it is not stored properly.

3. **Storage Requirements**: To prevent auto-ignition and ensure safety, white phosphorus cannot be stored in open air. Instead, it must be kept in a controlled environment.

4. **Storage Medium**: The safest way to store white phosphorus is in water. Water acts as a barrier, preventing contact with air and thus reducing the risk of ignition.

5. **Chemical Reactions**: When discussing white phosphorus, it is also important to note that it can react to form phosphorus pentoxide (P2O5), which is another highly reactive compound. However, the storage method remains the same; it is still stored in water to prevent reactions with air.

**Final Answer**: White phosphorus is stored in water.
