Assignment:
Q1) 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.
Q2) B does not react with any of the 1mol/L solutions above or the dilute sulfuric acid.
Q3) C reacts spontaneously with dilute sulfuric acid and with 1mol/L solutions of all the other metallic salts.
Q4) 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?
Provide complete and step by step solution for the question and show calculations and use formulas.
