Electrolytes (Simplified)

Next Topic

Electrolytes are compounds that can conduct electricity once they are dissolved in a solvent.

Understanding Electrolytes

Whenever you add a solute to a solvent there are three possible outcomes:the solute dissolves completely, dissolves partially or doesn't dissolve at all into ions.
