Question

(1) write two practical utilies of electrolysis.
(2) what are the products obtained at anole
and cathode, during the electrolysis of molts
sodium chloride​

Answer 1

1) Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

2) Electrolysis of Aqueous NaCl

Rather than producing sodium, hydrogen is produced. Electrolysis of aqueous sodium chloride: Electrolysis of aqueous NaCl results in hydrogen and chloride gas. At the anode (A), chloride (Cl-) is oxidized to chlorine. ... At the cathode (C), water is reduced to hydroxide and hydrogen gas.
