Doing an experiment about electroplating, you attempt to coat silver in gold using a basic electroplating set-up. You take the mass of the silver before and after the experiment. What can you say about the mass of the silver/gold product at the end of the experiment?

a. it's mass was greater than when it started

b. it's mass was lower than when it started

Samuel Kaiser · Answer 1

it's mass was greater than when it started

Explanation:

When a metal is coated with another metal, the plating metal deposits on the plated metal. Usually, the plating metal functions as the anode while the plated metal functions on the cathode. The anode metal is oxidized and reduced at the cathode and become deposited on the cathode material. This increases the mass of the cathode. Hence the mass of the silver/gold product is greater than the mass of silver at the beginning of the electroplating process.
