Name: An inert electrode and an active electrode.

Name: A positively charged non-metallic ion.

Name: The electrode at which reduction occurs.

Name: A non-metallic element which is a conductor of electricity.

Electrolysis is a redox process. Explain.

Identify the strong electrolytes among the following :

Acetic acid, ammonium chloride, ammonium hydroxide, carbon tetrachloride, dilute hydrochloric acid, sodium acetate, dilute sulphuric acid.

Identify the weak electrolytes among the following :

Acetic acid, ammonium chloride, ammonium hydroxide, carbon tetrachloride, dilute hydrochloric acid, sodium acetate, dilute sulphuric acid.

Identify the non-electrolytes among the following :

Acetic acid, ammonium chloride, ammonium hydroxide, carbon tetrachloride, dilute hydrochloric acid, sodium acetate, dilute sulphuric acid.

.

Explain why:

$\mathrm{Cu}$, though a good conductor of electricity is a non electrolyte.
