Chemistry coursework "how varying the concentration of an electrolyte affects the electrolysis current" Aim To test how varying the concentration of an electrolyte affects the eloctrolysis current using carbon electrodes with my chosen electrolyte, hydrochloric acid. Apparatus 2 carbon electrodes, beakers, an ammeter, a battery pack, wires, crocodile clips, electrode holder, hydrochloric acid, distilled water Diagram Plan I will set up the experiment as in the diagram and I will start by using the lowest mole 0.5 conc. I will measure 25mls of 0.5 m HCL using a burette for accuracy. I will put this in a beaker and weigh my two carbon electrodes. My chosen voltage is 6 v as this is a fairly low voltage that will give better results. I will run the current through the circuit for a few seconds only. This is because 1: -the electrodes wear down if they are in the process of electrolysis for too long. We do not want...
