Determine the volume of M/10 KMnO_4 solution required to react complet

1.	Determine the volume of M/10 KMnO_4 solution required to react completely with 25.0 mL of M/5 oxalic acid solution.
Answer» SOLUTION :The balanced CHEMICAL equation is `2KMnO_4+5(COOH)_2+3H_2SO_4rarr K_2SO_4+2MnSO_4+10CO_2+8H_2O` From the balanced equation , it is CLEAR that 2 mol of `KMnO_4 = 5 "mol of "(COOH)_2` `[(M_1V_1)/n_1]_(KMnO_4)=[(M_2V_2)/n_2]_((COOH)_2)` `1/10xxV_1/2=1/5xx(25.0)/5` or `V_1=(25.0xx10xx2)/(5xx5)=20.0mL`
