im very dissappointed. i needed to get 35 + in chemistry as it is a pre req for medicine. after all that umat preparation and getting an interview, it would suck balls if i dont get that 35 in chem.
im angry at myself more than the difficulty of the paper or the time ... i cant believe i made such stupid errors. the Cadmium one i basically disregarded 2 years of chemistry which said H+ conc decreases with increasing ph. thats what hurts. argh.
Sorry for scaling you down, Ankit.
By the way, the concentration of H+ DOES decrease! That's why pH increases! Cd is the reductant, H+ is reduced, H+ conc. is lowered, pH rises. You're not wrong.
With carbon, it will depend. I can't remember the question anymore.
Carbon should be fine, it's relatively inert. Platinum is the ultimate electrode - thus the possibility of it reacting like carbon does in the Hall-Heroult is nil.
