Sodium oxalate, Na2C2 O4, in solution is oxidized
to CO2 (g) by MnO, which is reduced to Mn2+.
A 50.1 – mL volume of a solution of MnO, is
required to titrate a 0.337
oxalate. This solution of Mno, is then used to
analyze uranium-containing samples. A 4.61 - g
sample of a uranium-containing material requires
32.5 mL of the solution for titration. The oxidation
of the uranium can be represented by the change
UO²+ → UO?+.
