Question

Explain electrolysis.........
​

Answer 1

Answer:

Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.

Electricity is the flow of electrons or ions. For electrolysis to work, the compound must contain ions. Covalent compounds cannot act as electrolytes because they contain neutral atoms.

The ions must be free to move, which is possible when an ionic substance is dissolved in water or it is melted. For example, if electricity is passed through molten lead bromide, the lead bromide is broken down to form lead and bromine.

Answer 2

Electrolysis, process by which electric current is passed through a substance to effect a chemical change.

The chemical change is one in which the substance loses or gains an electron (oxidation or reduction).
