Question

What is the net ionic equation for barium nitrate and hydrochloric acid?

Answer 1

Do you mean `"barium nitrate"` and `"sulfuric acid"`?

Explanation:

For `Ba(NO_3)_2(aq)` and `HCl(aq)` there would be no net macroscopic change. On the other hand, for `Ba(NO_3)_2(aq)` and `H_2SO_4(aq)`, a precipitate would form owing to the insolubility of `BaSO_4`:

`Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr`
