Answer 1

Potassium chloride (KCl) is a metal halide salt composed of potassium and

chlorine. It is odorless and has a white or colorless vitreous crystal appearance, with

a crystal structure that cleaves easily in three directions. Potassium chloride crystals

are face centered cubic. "Muriate of potash" is name which is occasionally

association with its use as a fertilizer containing 60% plant food as K2O.

Potash varies in colour from pink or red to

and is used primarily for making liquid starter fertilizers. It occurs naturally as the

mineral sylvite and in combination with sodium chloride as sylvinite.
