Electroplating uses electrolysis to put a thin layer of copper metal onto the cathode electrode. The copper at the anode releases copper ions and electrons, which move in the solution and combine to deposit copper metal on the cathode. This is known as electroplating. The concentration of the electrolyte is the number of reacting Cu ion particles in a given volume of copper nitrate electrolyte. With a higher concentration of electrolyte, more Cu ions are available for a reaction to occur. The number of collisions per unit time increases, which increases the rate of Cu metal production. There is a greater quantity of positive copper ions deposited at the cathode. As copper ions deposit forms at the cathode, the cathode gains mass. The rate of Cu metal production is determined by measuring the change in mass of the cathode electrode under a certain time frame i got an A grade for this
