occurring in aqueous solution, which statement correctly describes conservation of charge? (a) Net charge is

-4

on the left and

-2

on the right; charge is not conserved. (b) Net charge is

-2

on the left and

-2

on the right; charge is conserved. (c) Net charge is

-1

on the left and

-1

on the right; charge is conserved. (d) Net charge is

0

on both sides; charge is conserved.
