What is electrolysis?

1 Answer

Answer :

When current passes through an acid or a salt, it de-composes and the two decomposed portions tend to move in opposite direction. This process is called the electrolysis. Or the process of decomposing a liquid by the passage of electric current (DC) through it is called the electrolysis or electric analysis.
