When 25.00 mL of unknown were passed through a Jones reductor, molybdate ion (MoO4^2-) was converted into Mo3+. The filtrate required 16.43 mL of 0.010 33 M KMnO4 to reach the purple end point. MnO4- + Mo3+ --> Mn2+ + MoO2^2+. A blank required 0.04 mL. Balance the reaction and find the molarity of molybdate in the unknown.
