Problem- Cu2+ is reduced to Cu(s) at an electrode. If a current of 1.25 ampere is passed for 72 hours, what mass of copper is deposited at the electrode? Assume 100% current efficiency.
This is not a problem given in the book, so I just need the full solution of deriving!
Calculate the concentration of all species in a 0.100 M phosphoric acid solution. These species include [H3O+], [H2PO3-], [H3PO3], and [HPO32-]. For phosphoric acid, Ka1 = 3.0 x 10^-2 and Ka2 = 1.7 x 10^-7. (Only two of the hydrogens are ionizable..
