  1. Question 1

    Q1. In the Solvay process, the separation of Sodium bicarbonate from the reaction mixture depends on its solubility contrast with Sodium carbonate. Which is true?

    • A) NaHCO3 is less soluble in water than Na2CO3
    • B) Na2CO3 is less soluble in water than NaHCO3
    • C) Both have equal solubility in water
    • D) NaHCO3 is only soluble in hot alcohol

    Answer: NaHCO3 is less soluble in water than Na2CO3

    Explanation: Sodium bicarbonate is less soluble than Sodium carbonate, which allows it to precipitate in the Solvay process tower.
