Question

the following chemical reaction takes place in aqueous solution: snso₄(aq)+na₂s(aq)→sns(s)+na₂so₄(aq) write the net ionic equation for this reaction.

Explanation:

Step1: Write the complete ionic equation

$\text{Sn}^{2 + }(aq)+\text{SO}_{4}^{2 - }(aq)+2\text{Na}^{+}(aq)+\text{S}^{2 - }(aq)
ightarrow\text{SnS}(s)+2\text{Na}^{+}(aq)+\text{SO}_{4}^{2 - }(aq)$

Step2: Identify and cancel out the spectator ions

Spectator ions are $\text{Na}^{+}$ and $\text{SO}_{4}^{2 - }$. After canceling them out, we get the net - ionic equation.

Answer:

$\text{Sn}^{2 + }(aq)+\text{S}^{2 - }(aq)
ightarrow\text{SnS}(s)$
