Electrolytes are chemicals that break into ions (ionize) when they are dissolved in water. The positively-charged ions are called cations, while the negatively charged ions are called anions.  

Strong electrolytes completely ionize in water. This means 100% of the dissolved chemical breaks into cations and anions.

Weak electrolytes partially ionize in water. Pretty much any dissociation into ions between 0% and 100% makes a chemical a weak electrolyte, but in practice, around 1% to 10% of a weak electrolyte breaks into ions.

If a substance doesn’t ionize in water at all, it’s a nonelectrolyte.

Explanation:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

i believe the answer is three water molecules
