Hi. I have this problem I've been trying for a week and i still can't figure it out:
1. A reacts spontaneously with 1 mol/l BNO3, 1 mol/L D(N03)2 and dilute sulfuric acid. A does not react with 1 mol/L C(N03)2.
2. B does not react spontaneously with any of the the 1 mol/L solutions aove or with dilute sulfuric acid.
3. C reacts spontaneously with dilute sulfuric acid and with 1 mol/L solutions of all the other metallic salts.
4. D reacts spontaneously with 1 mol?L BN03. It does not react with dilute sulfuric acid.
a) Use these observations and arrange the following five reduction half-cell reactions in order, 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?
c) Which ion is the best oxidizing agent?
Ok so i do know that Hydrogen will be zero, but i don't know how the reactivity relates to the reduction potentials? I am so lost for this question! Any ideas would be really appreciated:)
