Sarah Lee An investigation to discover how the mass of deposited metal is related to the current that flows through an electrolyte An electroplating company needs to know how the mass of deposited metal is related to the current that flows through an electrolyte. I have been asked to investigate... Possible input variables The size of current, metal at the electrode, concentration of solution, surface area exposed to electrolyte and the time exposed the metal is exposed may effect the experiment. Possible output variables If I change any number of the input variables the mass of the metal deposited at the cathode and the mass lost at the anode will be affected. My input variable I have decided to change the current that I pass through the electrolyte. My outcome variable I will need to measure or observe the mass of metal deposited at the cathode. My control variable To make my experiment fair, I will keep the concentration of...
