Asample of a chromium-containing alloy weighing 3.450 g was dissolved in acid, and all the chromium in the sample was oxidized to 2cro42–. it was then found that 3.18 g of na2so3 was required to reduce the 2cro42– to cro2– in a basic solution, with the so32– being oxidized to so42–. write a balanced equation for the reaction of 2cro42– with so32- in a basic solution.
