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

Nov 22, 2016

$B a {\left(N {O}_{3}\right)}_{2} \left(a q\right) + N {a}_{2} C {O}_{3} \left(a q\right) \rightarrow B a C {O}_{3} \left(s\right) \downarrow + 2 N a N {O}_{3} \left(a q\right)$

#### Explanation:

And the net ionic equation is:

$B {a}^{2} + + C {O}_{3}^{2 -} \rightarrow B a C {O}_{3} \left(s\right) \downarrow$

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

Would you expect $B a C {O}_{3}$ to be more soluble in a weakly acidic solution? Why or why not?
