# How do barium nitrate and sodium carbonate react in aqueous solution?

Jan 25, 2016

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

#### Explanation:

All nitrates are soluble (in aqueous solution). All carbonates are INSOLUBLE (except for those of the alkali metals). Barium carbonate is certainly insoluble.

The net ionic equation for the above:

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

As for any equation, both mass and charge are conserved. What does this mean with respect to the 2nd equation?
