Question

How can you prepare lime water

Answer 1

By reacting CaO with Water --

CaO + H20 --- Ca ( OH )2 + heat

Ca(OH)2 is the lime water

Answer 2

Hey there !

Limewater is used in many science experiments and is easy to make on your own.

•Put 1 teaspoon of calcium hydroxide in a clean glass jar, up to 1 gallon in size. (Limewater is a saturated solution, which means there will be some extra chemical that doesn’t dissolve. A teaspoon will result in a fully saturated solution whether you use a gallon jar or a smaller one.)

•Fill the jar with distilled or tap water.

•Shake the jar vigorously for 1-2 minutes, then let it stand for 24 hours.

•Being careful not to stir up the sediment, pour the clearer solution off the top of the jar through a clean coffee filter or filter paper.

•Repeat the filtering step if necessary to obtain a clear limewater solution. Store in a clean jar or bottle.

•When carbon dioxide is bubbled into limewater, calcium carbonate (CaCO3) is produced. It precipitates out as a white suspended solid, making the solution appear cloudy.
