35. Solving a chemistry problem
749. From a sample of ore, 0.0800 g of uranium was transferred to U4 and titrated with 0.0100 N KMnO4.
2 MnO4- 5U4 2H2O=2Mn2 5UO22 4H.
Calculate the percentage of uranium in the ore from the following results of potentiometric titration:
V(KMnO4), ml 2.0 10.0 18.0 19.8 20.0 20.2 22.0
E, mV 301 330 359 389 1173 1486 1498
