Problem

The following equation is balanced for atoms but not for net charge:

\mathrm{2ClO^- + 3Br^- + 6H^+ \rightarrow 2Cl^- + Br_3^- + 3H_2O}

Which of the following identifies the net charge imbalance and the simplest modification that will correct it? a) Right side is 2 units more positive; add

2e^-

to the right side. b) Left side is 6 units more positive; add

6e^-

to the left side. c) Left side is 4 units more positive; add

4e^-

to the left side. d) Left side is 4 units more positive; add

4e^-

to the right side.
