Question

Write balanced chemical equations for the conversion of `CrO_4^(2-)` to `Cr_2O_7^(2-)` in acidic medium and `Cr_2O_7^(2-)` to `CrO_4^(2-)`
 in basic medium.

Solution

`K_2Cr_2O_7 + 2KOH -> 2K_2CrO_4 + H2O`

`2K_2CrO_4 + 2HCl -> K_2Cr_2O_7 + 2KCl + H_2O`

  Is there an error in this question or solution?
