Question

What forms at each electrode during the
electrolysis of concentrated sodium
chloride solution? I need an explanation because sodium and chloride are both non-metal so which goes to which electrode

Answer 1

Answer:

sodium is a metal

Chloride is a non-metal

you can also check the periodic table for checking if an element is a metal or non-metal .

Explanation:

Electrolysis of sodium chloride solution happens like this :                                                       When an electric current is passed through the concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms.
