Problem
Silver chloride is a sparingly soluble salt often used to illustrate precipitation reactions. The net ionic equation for its formation is
Ag+(aq)+Cl−(aq)→AgCl(s).
Answer the following questions about designing reactions that produce this precipitate.
(a) Describe the criteria you would apply in choosing aqueous reactants that, when combined, generate the net ionic equation above. In your discussion, include considerations of solubility rules and electrolyte strength.
(b) Provide one concrete example of a pair of aqueous reactants that meets the criteria you outlined in part (a) and write the corresponding balanced molecular equation with physical states.
(c) Suppose a student selected aqueous lead(II) chloride as one of the reactants. Predict the observable result when it is mixed with aqueous silver nitrate and explain why this choice fails to yield the target net ionic equation.
