If you titrate 1.0 g of H2O2 solution (30wt%) with KMnO4, 25.05 ml of this KMnO4 solution is used. What is the molarity of KMnO4?
How many coulombs are required?
Don't quite grasp the differences between end-to-end overlaps and side-to-side. I feel like it's commone sense that one is overlapped at the end and one at the side, but what all goes into that determiniation
