you take an unknown solution and measure 1ML of it into a flask. You dilute it with 25mL of water and 10mL of H2SO4. You titrate the solution with 19.80 mL of 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?
d) if 2 moles of electrons are required to oxidize 1 mole of unknown, what is the molarity of the unknown soln?
e) what piece of data is necessary to calculate the unknown's equivalent weight?
