Question

The following are examples of colloid except
A) milk B) starch in water C) Ammonium chloride solution D) butter. Give reasons for your answer.

Answer 1

Answer:

C)Ammonium chloride

Explanation:

A colloid, in chemistry, is a substance in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Ammonium Chloride is NH4Cl. In water it:

NH4-Cl = NH4(1+) + Cl(1-)

NH4(1+) + H2O = NH3 + H3O(1+)

So, you will have a solution of NH4(1+) + Cl(1-) + NH3 + H3O(1+) and it will all be dissolved.

Answer 2

answer is ammonia chloride
