Why are ionic precipitates washed with electrolyte instead of pure water?
Question:
Why are ionic precipitates washed with electrolyte instead of pure water?
Electrolytes:
An electrolyte is a substance that must first be dissolved to conduct electric currents. Electrolytes are important in the body's daily functioning as they regulate muscle contraction and ensure that the body does not dehydrate.
