Question

How do I solve this net ionic equation?

Answer 1

I think I am not supposed to split up solids, liquids, or gasses. So keep SO\[SO ^{2-}\] together?

Answer 2

in net ionic reactions you exclude spectator ions and only include those that are reacting: so you'd have Ba^+ (aq) + SO4^2- (aq) -> BaSO4 (s)

Answer 3

hence the word "net"

Answer 4

SO4 cannot be separated?

Answer 5

it can, but in this reaction it remains as a polyatomic ion

Answer 6

Why?

Answer 7

because it's stable and there is nothing to make it decompose

Answer 8

it makes the solid BaSO4.

Answer 9

SO4^2- could decompose into O2 and SO2

Answer 10

oh, so it combines with Ba^2+ to make BaSO4?

Answer 11

yep which precipitates out, hence the subscript "(s)"

Answer 12

The two compounds balance out in the end?

Answer 13

yep their charges balance each other out, Ba is 2+ SO4 is 2-

Answer 14

Thanks dude.

Answer 15

no prob
