# In the reaction between silver nitrate and sodium chloride, what is the role of nitrate and sodium ions in solution?

Nov 1, 2015

Both $N {a}^{+}$ and $N {O}_{3}^{-}$ will be spectators.

#### Explanation:

We go back to simple solubility rules. All alkali metals salts are soluble. All nitrates are soluble. All halides are soluble (except for those of $A {g}^{+}$ and $H {g}_{2}^{2 +}$). All hydroxides are insoluble (except for previous).

So the net ionic equation representing the reaction is:

$A {g}^{+} + O {H}^{-} \rightarrow A g O H \left(s\right) \downarrow$

Silver hydroxide is not a well-characterized species. Its likely formulation is $A {g}_{2} O \cdot \left(O {H}_{2}\right)$, a hydrous oxide of silver, but you don't need to know this in 6th form.
