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.

Solution f has a ph of 11, and solution g has a ph of 13. how does the concentration of hydroxide ions in solution f differ from solution g? solution g has three times as many hydroxide ions as solution f. solution g has 100 times more hydroxide ions than solution f. solution f has 100 times more hydroxide ions than solution g. solution f has three times as many hydroxide ions as solution g.
