Question
What are cations and anions ? Give an example of each.
Solution
Cations: The positively charged ions formed, when a chemical compound dissolves in water are called cations. During electrolysis, Cations are discharged at cathode. Example – sodium (Na+) from common salt NaCl.
Anions: The negatively charged ions formed, when a chemical compound dissolves in water are called anions. During electrolysis, Anions are discharged at Anode. Example – Chlorine (Cl-) from common salt NaCl.
