When 25.0 mL of unknown were passed through a Jones reductor, molybdate in (MoO4 2+) was converted to Mo3+.
When 25.00 mL of unknown were passed through a Jones reductor, molybdate ion (Mo02) was converted to Mo3+. The filtrate required 16.43 mL of 0.01033 M KMn04 to reach the purple endpoint 3Mn05 + 5M034 + 4H+ → 3Mn2+ + 5 M002+ + 2H20. A blank required 0.04 mL. Find the molarity in the unknown.
