Answer
Strong Electrolyte
A substance that completely dissociates into ions in water and conducts electricity very well is called a strong electrolyte.
Examples – sodium chloride (NaCl) and potassium nitrate (KNO₃).
Cathode and Anode
The electrode where reduction takes place and which attracts cations during electrolysis is called the cathode.
The electrode where oxidation takes place and which attracts anions during electrolysis is called the anode.
