Consider the following statements : 1. Baking soda is used in fire extinguishers. 2. Quick lime is used in the manufacture of glass. Which of the statements given above is/are correct ?

Result
Your answer: —  Â·  Correct: C
Explanation

Statement 1 is correct as baking soda (sodium hydrogencarbonate) is a key component in soda-acid and dry chemical fire extinguishers [1][t1]. When heated, it decomposes to release carbon dioxide gas, which helps smother flames by displacing oxygen [c3][t5]. Statement 2 is also correct. Quick lime (calcium oxide) is a fundamental raw material in the manufacture of glass, particularly soda-lime glass, which accounts for approximately 90% of all manufactured glass [t3]. In the glass-making process, silica, soda ash, and lime (derived from quicklime or limestone) are melted together; the lime acts as a stabilizer, providing chemical durability and insolubility to the finished glass product [t6][t7]. While quick lime is also used in cement production [c4], its role in the glass industry as a source of calcium oxide is well-established in industrial chemistry.
