When water is added to compound (A) of calcium, solution of compound (B) is formed. When carbon dioxide is passed into the solution, it turns milky due to the formation of compound (C). If excess of carbon dioxide is passed into the solution milkiness disappears due to the formation of compound (D). Identify the compounds A, B, C and D Which compounds correspond to A, B, C, and D in the following chemical reactions?

Options

  1. AA = Calcium hydroxide, B = Calcium hydroxide, C = Calcium bicarbonate, D = Calcium chloride
  2. BA = Calcium oxide, B = Calcium sulfate, C = Calcium carbonate, D = Calcium chloride
  3. CA = Calcium chloride, B = Calcium carbonate, C = Calcium chloride, D = Calcium bicarbonate
  4. DA = Calcium sulfate, B = Calcium carbonate, C = Calcium bicarbonate, D = Calcium chloride

Correct answer

A. A = Calcium hydroxide, B = Calcium hydroxide, C = Calcium bicarbonate, D = Calcium chloride

Step-by-step solution

Correct Option is : (A) A = Calcium hydroxide, B = Calcium hydroxide, C = Calcium bicarbonate, D = Calcium chloride
