Excess of carbon dioxide is passed through 50 mL of 0.5 M calcium hydroxide solution. After the completion of the reaction, the solution was evaporated to dryness. The solid calcium carbonate was completely neutralized with 0.1 N hydrochloric acid. The volume of hydrochloric acid required is (atomic mass of calcium = 40):
- 300 cm3
- 200 cm3
- 500 cm3
- 400 cm3
Answer
(C) 500 cm 3
