Problem

A particulate-level snapshot shows a precipitation reaction in aqueous solution. • BEFORE mixing: 6 Na⁺ ions, 6 Cl⁻ ions, and 4 Ag⁺ ions are dispersed in the water. • AFTER the reaction is complete and the solid is removed: the solution contains 6 Na⁺ ions and 2 Cl⁻ ions; the separated solid consists of 4 formula units of an insoluble compound. Which net ionic equation is most consistent with these observations? a) Na++Cl−→NaCl(s)Na^{+} + Cl^{-} \rightarrow NaCl(s) b) Ag++Cl−→AgCl(s)Ag^{+} + Cl^{-} \rightarrow AgCl(s) c) 2Ag++2Cl−→2AgCl(s)2Ag^{+} + 2Cl^{-} \rightarrow 2AgCl(s) d) Ag++Cl−→AgCl(aq)Ag^{+} + Cl^{-} \rightarrow AgCl(aq)
