Question

Is quick lime the same as limewater?

Answer 1

Quick lime is CaO (calcium oxide)

Slaked lime is Ca(OH)2 (calcium hydroxide)

Lime water is just a dilute solution of calcium hydroxide.

Soda lime is a mixture of about 75% calcium hydroxide, a few percent each of sodium hydroxide and potassium hydroxide, and about 20% water. It is commonly used to adsorb CO2 from the air.
