NH3 can be used. Cr3+ gets preicpitated with NH3 but not Ag+
Cr3+ (aq) + NH3 + H2O ---> Cr(OH)3 (s) + 3NH4+ (aq)
Ag+ (aq) + NH3 excess --> [Ag(NH3)2]+ (aq) soluble complex

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...

Name Experiment 5- Post-lab Questions 1. In Reaction B, you observed magnesium metal reacting with a hydrochloric acid solution to produce hydrogen gas and a magnesium chloride solution. Another reaction that has a gaseous product is the reaction of a hydrochloric acid solution (HCl(ag)) with sodium sulfite (Na,so,(ag)) solution to produce a sodium chloride solution (NaCl(aq)) and gaseous sulfur dioxide (S0,(g)). Write a balanced chemical equation for this reaction. 2. The sulfur dioxide produced by aqueous chemistry in the previous...
