A50.00 ml solution containing an unknown amount of uo2−4 was passed through a jones reductor, converting uo2−4 to u3+. upon exposure to atmospheric oxygen, the u3+ was reoxidized to u4+. the solution was then diluted to 100.0 ml using 1 m h2so4 and titrated with 19.84 ml of 0.0989 m kmno4 to reach the purple endpoint. a blank solution subjected to the same procedure required 0.15 ml. balance the titration reaction and determine the concentration of uo2−4 in the original solution.
