How do you purify calcium hydroxide?

Answer 1

You put your left hand in, you put your left hand out, you put your left hand it and shake it all about. Do the hokey pokey, and turn yourself around, and that's how you purify calcium hydroxide.

Answer 2

ADD WATER. The process is called SLAKING. Add water to calcium oxide - sometimes called quicklime, and the result is calcium hydroxide, sometimes called slaked lime.

CaO + H2O = Ca(OH)2
