Practice Electrolyte in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A substance that dissociates into free ions when dissolved in a solvent (typically water), producing a solution that can conduct electric current.
Salt dissolved in water breaks into charged particles (ions) that carry electric current.
