Question

0.6 (a) Solution of a substance X is used for testing carbon dicode Write the equation
of the reaction
of X with carbon dioxide
(b) How is X' obtained ? Write chemical equation.​

Answer 1

Answer:

Substance X is lime water.

Ca(OH)2 + CO2 → CaCO3 + H2O

Ca(OH)2 -(Lime water)

CO2 -(Carbon dioxide)

CaCO3 -(Calcium carbonate)

H2O - (Water)

(ii) Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat.

CaO(s) + H2O(l)→ Ca(OH)2(ag)

CaO(s) - (Quicklime)

Ca(OH)2(ag) - (slaked lime)
