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»

sodium is a metalChloride 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.
