Cr Barium sulfate 17. occurs when aqueous hydroiodic acid and aqueous strontium sulfide are B. Cr This means that you can write. The first thing I notice is that the product side has 3 sulfate groups, while the reactant side has only 1. Why does strontium sulfate becomes less soluble in an aqueous solution when sodium sulfate is added? These ions are called spectator ions because they do not participate in the actual reaction. The net ionic equation is as follows: \(Pb^{2+} (aq) + 2I^-(aq) \rightarrow PbI_2(s) \). Write a molecular equation for the precipitation reaction that occurs (if any) when each pair of aqueous solutions is mixed. (7.6.1) AgNO 3 ( aq) + K 2 Cr 2 O 7 ( aq) Ag 2 Cr 2 O 7 . Thus precipitation reactions are a subclass of exchange reactions that occur between ionic compounds when one of the products is insoluble. Zinc iodide 10. potassium sulfate and strontium iodide Express your answer as a chemical equation.
