AMMONIUM PERCHLORATE:

A perchlorate anion becomes a contaminant in water due to the dissolution (dissolving) of ammonium, potassium, magnesium, or sodium perchlorate salts in water. Ammonium perchlorate dissolves easily in water and, like table salt, does not require special conditions such as a low pH or high temperature to dissolve as other salts might. Get price
