Aim: To investigate how the concentration of the electrolyte affects the amount of metal deposited at the cathode while electroplating. Hypothesis: An increase in concentration of an electrolyte increases the rate of electroplating. When an electrolyte. Greater the concentration of electrolyte, greater is the concentration of metal ions. Discharging occurs faster when there is a greater concentration of ions. Therefore, an increase in concentration will lead to faster electroplating.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
