- Why do you subtract the volume of a drop off the volume dispensed after reaching the end point of the titration.
- A student adds ten mL of .02M permanganate to a sample containing peroxide solution. The solution remains clear after the addition of the permanganate. Which reactant is limiting? Which reactant is in excess?
