Question

Please Balance. I watched the videos but still cant. Br2 + S2O32– + H2O → Br1– + SO42– + H+

Answer 1

you need to split this redox reaction into two separate half-reactions, balance each one separately, then combine them

Answer 2

the difficult part is making sure the charges balance, and the easiest way is not to balance the whole thing at once, but split into smaller pieces
