Question

Answer 1

Answer #1

BrO3 - ------> Br-

1) Balancing 'O' by adding H2O;

BrO3 - -----> Br- + 3H2O

2) Balancing 'H' by adding H+ ion

BrO3 - + 6H+ ------> Br- + 3H2O

3) Balancing charge by adding electrons i.e. e-

BrO3 - + 6H+ + 6e- ----> Br- + 3H2O

Now everything is balanced.

So, electrons transferred = 6 ....Answer
