Question #9d191

Answer 1

Opposite charges attract.

Explanation:

Remember that in electrolysis, the cathode is negative, and the anode is positive. A mnemonic to remember that is PANIC (Positive Anode, Negative is Cathode). Since silver ions `(Ag^+)` are cations, they are positive in charge.

A fundamental fact in physics and chemistry is that opposite charges attract, like-charges repel. In here, silver ions are positive, so they will be attracted to the cathode, because it is negative.

Here is the picture of electroplating of silver:
