Question

Suspension of slaked lime in water is known as
(a) lime water (b) quick lime (c) milk of lime (d) Aqueous solution of slaked lime

Answer 1

Answer: (c). Suspension of slaked lime in water is known as milk of lime

Calcium hydroxide is prepared by adding water to quicklime (CaO).
$\underset{Quicklime}{CaO\left(s\right)}+H_{2}O\left(l\right)⟶\underset{Slakedlime}{Ca\left(OH{)}_2\right(s)}$
It is a white amorphous powder. It is sparingly soluble in water.
So, it forms a suspension of slaked lime in water which is called milk of lime and the clear solution obtained after the suspension settles is known as lime water.
