Question

The formulae of slaked lime and quick lime
respectively are
(1) Ca(OH)2, CaO (2) CaO, Ca(OH)2
(3) CaCO3, Ca(OH)2 (4) Ca(OH)2, CaCO3

Answer 1

1) Ca(OH)2 is Slaked lime and CaO is quick lime.

Extra information :-)

Slaked lime is also known as Calcium hydroxide and quick lime is also known as limewater or calcium oxide.

Hope it helps!!

Answer 2

The chemical formula for lime is CaCO3 .

When lime is dissociated then it produces quick lime and carbon dioxide .

CaCO3 → CaO +CO2

So, the chemical formula of quick lime is CaO.

When quick lime reacts with water it produces lime water or slaked lime .

CaO + H2O → Ca(OH)2

So, the chemical formula of slaked lime is Ca(OH)2 .
