Summary Introduction
To review:
The liquid, out of the three, which conducts
Introduction:
The substance which when dissolved in water dissociates into ions is known as an electrolyte, whereas the substance which does not conduct electricity due to the presence of a covalent bond is known as a non-electrolyte. A solution containing ions does conduct electric current through it.
