Consider the following statements:
Which of the statements given above is/are correct?
Option (D):
Statement 1 is correct: Baking soda, chemically known as sodium bicarbonate (NaHCO₃), is utilized in certain types of fire extinguishers. When heated, it decomposes to release carbon dioxide (CO₂), which acts as a fire suppressant by displacing oxygen, and water, which contributes to cooling. The decomposition reaction is: 2 NaHCO₃ → Na₂CO₃ + CO₂ + H₂O.
Statement 2 is correct: Quick lime (calcium oxide, CaO) is a key raw material in the manufacture of glass. It functions as a flux, aiding in the fusion of silica (SiO₂) and soda (Na₂CO₃) to form a stable glass composition.
Statement 3 is correct: Gypsum (CaSO₄·2H₂O) is the primary material used in the production of plaster of Paris. Upon heating to approximately 150°C, gypsum loses three-quarters of its water of crystallization to form plaster of Paris (CaSO₄·½H₂O).
Options (1), (2), and (3) are incorrect because all three statements provided are factually accurate. Therefore, the option that includes all three statements is the correct choice.
