Part C:
Multiple choice:
What is the conjugate acid of C6H5NH2?
B) C6H5NH3+

Part D:
For the chemical equations shown below, label each reactant as either acid or base, and each product as either conjugate acid or conjugate base according to the Brønsted-Lowry definition.
HPO4^2- (aq)(base) + H2O(I)(acid) ---> H2PO4^-(aq)(conjugate acid) + OH^-(aq)(conjugate base)

HPO4^2-(aq)(acid) + H2O(I)(base) ---> PO4^3-(aq)(conjugate base) + H3O^+(aq)(conjugate acid)
