25.0 cm3 of a 0.0500 m solution of sodium oxalate (Na2C2O4) reacted with 24.8 cm3 of a solution of KMnO4, A, in the presence of excess H2SO4.
25.0 cur' of a 0.O494 m solution of NH2OH in H2SO4 was boiled with an excess of iron(III) sulfate solution, and when the reaction was complete, the iron (IT) produced was found to be equivalent to 24.65 cm3 of solution A. The product B formed from the NH?OH in this reaction can be assumed not to interfere with the determination of iron(II). What can you deduce about the identity of B?
We need at least 10 more requests to produce the solution.
