Using pEo to Predict Reaction ...

Hi all,

Newbie here :P

I was just wondering if anyone could comment on the following:

Using the following two equations,
Sn+4 + e- → Sn+3 (pEo = 7.2)
Be+3 + e- → Be+2 (pEo = 2.5)

Do we expect Sn+4 to reduce Be+3? And why would that be ?

I need a second opinion on it, and would really appreciate it if anyone could drop me a line.

Thanks and regards,
Theresa

It doesn't. The preferred oxidation state of Sn is +4.
Your Be+3 should be going out oxidizing others to become a +2.
