    can someone please explain to me what electrolysis is?

    when two plates are charged one positively and one negatively. The ions are then attracted to the negative plate, and thats where my knowlegde ends, we havent covered it much in physics

    It's studied in Chemistry rofl.

    Electrolysis is the breaking down of a compound that contains ions, down to its elements using an electric current.
    The negative ion in compound move to the anode, and the positive ions in compound move to the cathode.

    Lol, ignorant comment much? We do study it in the context of electricity and ions in Physics, just briefly as a real life example, hence my basic knowledge. Why do you consider there to be no crossover between Physics and Chemistry anyway?

    "gcse chemistry: what is electrolysis?"

    Lol, assumptions much? I never said there was no crossover.

    Electrolysis

    *Electrolysis is the breaking down of something using electricity
    *It needs a liquid (called an electrolyte) to conduct the electricity
    *It's the free ions in the molten substance that allow electricity to be conducted.
    *For an electrical circuit there needs to be a flow of electrons. In electrolysis, electrons are taken away from ions at the positive electrode and given to other ions at the negative electrode. As the ions gain or lose electrons they become molecules or atoms.

    Example of Electrolysis

    *Aluminum can be taken from its ore.
    *The main ore of aluminum is bauxite which contains aluminum oxide which is Al2O3.
    *Molten aluminum oxide contains free ions to conduct electricity.
    *The positive aluminum ions are attracted to the negative electrode where they pick up electrons to get a full shell...these then become aluminum atoms with NO charge.
    *They sink to the bottom.

    *Whereas the negative oxygen ions are attracted to the positive electrode where they lose two electrons. This the makes an oxygen molecule which can be bubbled off.

    I would give examples of equations if I thought these would help and if I understood how to insert all the charges and stuff on this forum.

    Anymore questions just ask.
