In $\text{ammonium sulfate}$?

#### Explanation:

${\left(N {H}_{4}\right)}_{2} S {O}_{4}$. The most common use of this material is as an agricultural fertilizer. In aqueous solution it would speciate to $S {O}_{4}^{2 -}$ and $N {H}_{4}^{+}$ ions:

${\left(N {H}_{4}\right)}_{2} S {O}_{4} \left(s\right) + \text{excess water} \rightarrow 2 N {H}_{4}^{+} + S {O}_{4}^{2 -}$
