I did an experiment for the electrolysis of dilute sulphuric acid. In my report, I am required to draw two diagrams showing,
a) the movement of ions to the anode and the cathode
b) the discharge of ions at the anode and at the cathode
I know the ions present in dilute sulphuric acid are SO4(2-), H(+) and OH(-). I also know that the ions discharge at the anode are OH(-) ions whereas H(+) ions are discharged at the cathode.
BUT,
I DON'T KNOW HOW TO DRAW THE DIAGRAMS!!! Am I supposed to point arrows from the ions to the electrodes for the movement of ions? How about discharge? Should i draw the discharged ions sticking to the electrodes? Or arrow pointing towards the discharged ions from the electrodes? And if only OH(-) and H(+) ions are discharged, what happens to the SO4(2-) ions???
PLEASE HELP ME! My report is due TOMORROW!
