A precipiation reaction occurs when a solution containing a cation (red spheres) and a solution containing an anion (green
Question 35 of 42 sphres) are mixed. The spectator ions have been omitted from the diagram for clarity,
Which set of reactants best represents the diagram?
\( \mathrm{Li}_{2} \mathrm{SO}_{4}(\mathrm{aq})+\mathrm{AgNO}_{3}(\mathrm{aq}) \)
\( \mathrm{NaClO}_{4}(\mathrm{aq})+\mathrm{CaCl}_{2}(\mathrm{aq}) \)
\( \mathrm{KNO}_{3}(\mathrm{aq})+\mathrm{CuCl}_{2}(\mathrm{aq}) \)
\( \mathrm{NH}_{4} \mathrm{Br}(\mathrm{aq})+\mathrm{Pb}\left(\mathrm{C}_{2} \mathrm{H}_{3} \mathrm{O}_{2}\right)_{2}(\mathrm{aq}) \)
Incorrect Answer
Write the net ionic equation for the reaction. Include physical states.
net ionic equation:
\[
\begin{array}{l}
\mathrm{Pb}^{2+}(\mathrm{aq})+2 \mathrm{Br}^{-}(\mathrm{aq}) \longrightarrow \mathrm{PbBr}_{2}(\mathrm{~s}) \\
\text { Incorrect Answer }
\end{array}
