you take an unknown solution and measure 1mL of it into a flask. You dilute it with 25mL of water and 10mL of 1 M H2SO4. You titrate the solution with 19.80 mL of .5M KMnO4. The (MnO4)- is reduced to (Mn) 2+ by the unknown solution.
a) What is the equivalent weight of (MnO4)- for the experiment?
b) How many equivalents of electrons were delivered to the unknown soln?
c) What is the normality of the unknown solution?
