    Electrolyisis with saltwater and aluminum cathode

    I'm doing an electrolysis experiment using table salt, distilled water, and aluminum as my anode (bought it from brumer.com). After putting a current through it, bubbles start to form. I know I'm producing Hydrogen and Chlorine gas, and creating Sodium Hydroxides and other Aluminum...

    Electrolytic cell 1.0M H2SO4, reaction at cathode?

    Hi, I'm stuck on this question from electrochemistry in Hebden, grade 12. 1.0M H2SO4 electrolyzed, what is the reaction at the cathode? Since cathode is negative, positive ions would be attracted to it. But the answer has the half equation of SO4 2- as the answer. Since SO4 2- is negatively...

    Electrolysis Help

    Could you please help me with this: I'm doing an electrolysis lab in which I am plating copper. Here is the setup: The output of a DC power supply is hooked up to an ammeter (to measure the amperage) which is then connected to an Fe cathode. The Fe cathode is in a beaker containing a Cu...
