Which of the following compound is used as fire extinguisher?
- A \(\mathrm{NaHCO}_{3}\)
- B \(\mathrm{Na}_{2} \mathrm{CO}_{3}\)
- C \(\mathrm{NaOH}\)
- D \(\mathrm{Na}_{2} \mathrm{SO}_{4}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{NaHCO}_{3}\)
Step-by-step Solution
Detailed explanation
When the fire extinguisher is operated by pressing the knob on it, the sulphuric acid gets mixed with sodium bicarbonate solution producing a lot of carbon dioxide gas. Carbon dioxide gas is neither combustible nor helps combustion. Hence, sodium bicarbonate is used in fire extinguishers
