Title: Redox stoic(Urgent please)
Post by: vijayamac on November 19, 2006, 05:34:02 PM

Thanks for your reply.

My balanced eqaution is
5 Sn2+  +  16H+  +     2MnO4- ----> 5 Sn4+  +2Mn2+   +8H2O

We haven't learnt Nernst equation. This problem is under Redox Stoic.

It would be very helpful if you can solve and give me the final answe for part (b). I am struggling in my AP Chem class.

Thanks again

I have a major test in elctrochemistry unit.

can you PLEASE answer this question ASAP.Thank you so mcuh

In an acidic solution MnO4- reacts with Sn2+ to give Sn4+ and Mn2+

a.Write a balanced equation for the reaction
b.38.62 mL of 0.100M solution of KmnO4  is needed to titrate 40.0ml of  Sn2+  solution. How many moles of  Sn2+  are present in the solution?


I know the answer for the first part fo tehe question. can you answer the (b) part?
