Chemistry question (about Equivalence point) ? please help.?

[JAMES699]

A student titrated a sample of an acidified tin (II) chloride solution with potassium permanganate.

2MnO4 - (aq) + 16 H+(aq) + 5Sn^2+(aq) ----> 2 Mn^2+(aq) + 8H20(l) + 5Sn^4+(aq)

---------------------------------
When would the equivalence point of this titration be reached? Be specific. Give the actual mole ratio of the oxidizing agent and reducing agents.

Thanks 4 your help.
