Observations:
1) A reacts spontaneously with 1mol/L BNO3, 1mol/L D(NO3)2 and dilute sulfuric acid.A does not react with 1mol/L C(NO3)2.
2) B does not react with any of the 1mol/L solutions above or the dilute sulfuric acid.
3) C reacts spontaneously with dilute sulfuric acid and with 1mol/L solutions of all the other metallic salts.
4) D reacts spontaneously with 1mol/L BNO3. It does not react with the dilute sulfuric acid.

a) Use these observations and arrange the following five reduction half-cell reactions in order, from the one with the largest positive reduction potential listed first:

A^(2+)+2e->A(s)
B^(+)+e->B(s)
C^(2+)+2e->C(s)
D^(2+)+2e->D(s)
2H(+)+2e->H2(g)

b) Which metal is the best reducing agent and which ion is the best oxidizing agent? Is the dilute sulfuric acid the salt bridge?
