Question

What is the equation for this reaction: Barium Nitrate + Sodium Carbonate?

Answer 1

`Ba(NO_3)_2(aq) + Na_2CO_3(aq) rarr BaCO_3(s)darr + 2NaNO_3(aq)`

Explanation:

And the net ionic equation is:

`Ba^2+ + CO_3^(2-) rarr BaCO_3(s)darr`

Barium carbonate is quite insoluble in aqueous solution, `K_"sp"=2.58xx10^(−9)`, and should precipitate in this `"metathesis (partner exchange) reaction"`

Would you expect `BaCO_3` to be more soluble in a weakly acidic solution? Why or why not?
