Balance the following equation in an acidic and basic medium

* Cr^(+3)+BrO^(-)--->CrO4^(2-)+Br^(-)

2 answers

Cr^3+ + 4H2O==> CrO4^2- + 3e + 8H^+
BrO^- + 2e + 2H^+ ==> Br^- + H2O
--------------------------------

Multiply eqn 1 by 2 and eqn 2 by 3, then add to obtain the complete balanced redox equation.

Is it in basic medium
