When 23.00 mL of unknown were passed through a Jones reductor, molybdate ion (Moo42 was converted into Mo The filtrate required 16.42 mL of 0.01034 M KMno4 to reach the purple end point.

Explanation / Answer

Jones reductor

MoO4 2- + Zn(s) + 8H+ è Mo3+ + Zn2+ + 4H2O

[MoO4 2+] = (16.35 mL MnO4 - )(0.01034 M MnO4 - )*(5 mmol MoO4 2+/3 mmol MnO4 - )/(23.00 mL)

= 0.01225M MoO4----------answer

16.42 -0.07=16.35 mL MnO4 -
