Sides of match box have coating of

Options

A. Potassium chlorate, red lead
B. Potassium chlorate , antimony sulphide
C. Antimony sulphide, red phosphorus
D. Antimony sulphide, red lead

Answer

**Step-by-Step Solution:**

1. **Understanding the Components of a Matchbox:**
- The sides of a matchbox are designed to ignite the matchsticks when struck against them. This requires a specific chemical composition that can facilitate combustion.

2. **Identifying the Coating on the Sides:**
- The sides of a matchbox are typically coated with a mixture that includes **Red Phosphorus** and **Antimony Sulfide**. These substances are chosen for their properties that allow for safe ignition when the match is struck.

3. **Role of Potassium Chlorate:**
- While Potassium Chlorate is a common oxidizing agent used in the match head (the tip of the match), it is not the primary coating on the sides of the matchbox. The match head contains Potassium Chlorate along with other components to facilitate ignition.

4. **Safety Considerations:**
- It is important to note that some of these chemicals, particularly Antimony Sulfide and Lead, can be toxic. Therefore, safety measures are important when handling matches.

5. **Conclusion:**
- In summary, the sides of a matchbox are coated with **Antimony Sulfide** and **Red Phosphorus**, which are essential for the ignition process of the matchsticks.
