the oxidation and half-reaction of a redox reaction is Sn*2+ --> Sn *4 +2e- and the reduction half-reaction is Au*3+ +3e- -->Au

what minimum numbers of tin (II) ions and gold (III) ions would have to react in order to have no electrons left over???

Phys... is indeed correct. You multiply the equations by his numbers and add them up:

3Sn*2+ ===> 3Sn*4+ + 6e-
2Au*3+ +6e- ===> 2Au
draw a line under the bottom

With respect to gatorboi, it is obvious that tin in the oxidation state of +2 will react vigorously with gold in the oxidation state of +3. This is because gold is a very unreactive metal. Given a chance, gold(III) will take electrons from almost anything to get back to gold(0).

3 Sn 2+ and 2 Au 3+ need to react.

3 Sn2+ will donate a total of 6 e-. 2 Au 3+ will accept a total of 6 e-.

Hey Bebe,
You do not seem novice because the questions you are asking are obvious. You answered you own question. and I think that if you did the electron loss sentences then you must know to mutlitpy the electrons. also if you know this much you know that Tin and Gold are not likely to react with each other.
