Problem
A compound (A) is used in preparation of washing soda to recover ammonia in Solvay's process. When is bubbled through an aqueous solution of (A), the solution turns milky. It is used in white washing due to disinfectant nature. What is the chemical formula of A? a. b. c. d.Intuitive explanation
The key is recognizing that compound A plays a dual role: it's essential for ammonia recovery in the Solvay process AND produces a milky precipitate with . The milkiness comes from calcium carbonate forming when reacts with a calcium compound. Since A is also used for whitewashing with disinfectant properties, you're looking for a calcium compound that fits all three clues—think about what calcium compound is produced as a byproduct in Solvay's process and has antimicrobial properties.
