Consider the below statements and identify the correct answer.

Statement-I: The chemical formula for baking soda is NaHCO₃.

Statement-II: It is used in soda-acid fire extinguisher.

Correct option is A

Correct Answer: A Both the statements are true

Explanation:

1. Statement-I: "The chemical formula for baking soda is NaHCO₃."
• This statement is true.
• Baking soda, also known as sodium bicarbonate, has the chemical formula NaHCO₃. It is a white crystalline compound commonly used in baking as a leavening agent, as well as in various household and industrial applications.
2. Statement-II: "It is used in soda-acid fire extinguisher."
• This statement is also true.
• Baking soda (NaHCO₃​) reacts with acid (typically sulfuric acid or vinegar in soda-acid fire extinguishers) to produce carbon dioxide (CO₂) gas.
• The reaction: NaHCO₃+H+→Na⁺⁺CO₂+H₂O
• The released CO₂ gas forms a blanket over the fire, cutting off the oxygen supply and extinguishing it effectively.

Information Booster:

•  Baking soda is also used for cleaning, deodorizing, and as an antacid to neutralize stomach acid.
• In addition to soda-acid fire extinguishers, carbon dioxide fire extinguishers are widely used for electrical and chemical fires.
• Sodium bicarbonate is thermally unstable and decomposes when heated, producing CO₂ gas, which is also utilized in baking.
• The principle of soda-acid fire extinguishers relies on the production of CO₂, a non-flammable gas that displaces oxygen.
• Alternatives like dry chemical extinguishers are now more common due to easier maintenance and handling.
