Write the net ionic equation for each of the following reactions?

BaI2(aq) + K2SO4(aq) -> BaSO4(s) + 2 KI (aq)

K2CO3(aq) +2 HCl(aq) -> 2 KCl(aq) + CO2(g) + H2O(l)

Answer 1

The aquated ions are not considered in the net ionic equations. Only the materials that precipitate or are evolved as gases are of interest.

#Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr# Barium sulfate is reasonably insoluble.

#CO_3^(2-) + 2H^+ rarr H_2O(l) + CO_2(g)uarr# The potassium salts are along for the ride, and need not be considered. Carbonate anion undergoes an acid base reaction, and liberates gaseous carbon dioxide.

It is necessary that mass and charge be conserved in both cases.

Sure, I'd be happy to help. Could you please provide the reactions you'd like the net ionic equations for?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

BaI2(aq) + K2SO4(aq) -> BaSO4(s) + 2 KI (aq) K2CO3(aq) +2 HCl(aq) -> 2 KCl(aq) + CO2(g) + H2O(l)

BaI2(aq) + K2SO4(aq) -> BaSO4(s) + 2 KI (aq)

K2CO3(aq) +2 HCl(aq) -> 2 KCl(aq) + CO2(g) + H2O(l)
