Question

How will you prepare slaked lime?

Answer 1

• The chemical name of slaked lime is calcium hydroxide and its chemical formula is $\mathrm{Ca}{\left(\mathrm{OH}\right)}_2$.

Preparation of slaked lime :

• The reaction between calcium oxide commonly known as lime and water produces slaked lime.
• It is an exothermic reaction (the reaction in which heat is released).

$$\begin{gathered} \mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\stackrel{}{\to }\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right) \\ \left(\mathrm{Lime}\right)(\mathrm{Slaked}\mathrm{lime}) \end{gathered}$$
