87. Solving a chemistry problem

45th century Titration of a solution containing uranium (IV). carried out by the coulometric method using cerium (IV) ions, which are electrogenerated in a sulfuric acid solution at a constant current strength of 5.0 mA. The equivalence point was determined amperometrically, while the electrolysis time τ was:
