Final answer:
The net ionic equation for the reaction between AgNO3 and KCl in aqueous solution, forming an insoluble precipitate of AgCl, is Ag+ (aq) + Cl- (aq) → AgCl (s).
Step-by-step explanation:
The question at hand is about finding the net ionic equation for the reaction between silver nitrate (AgNO3) and potassium chloride (KCl) in aqueous solution. To identify the reacting species in the solution, we write the complete ionic equation and then cancel the spectator ions, which are the ions that do not participate in the actual reaction. The net ionic equation only includes the ions that form the insoluble compound.
Upon mixing AgNO3 and KCl in an aqueous solution, AgCl, a silver chloride precipitate, is formed. The complete ionic equation for the formation of AgCl would be:
Ag+ (aq) + NO3− (aq) + K+ (aq) + Cl− (aq) → AgCl (s) + K+ (aq) + NO3− (aq)
Here, the potassium (K+) and nitrate (NO3−) ions are spectator ions and therefore can be eliminated from the equation, leading to the net ionic equation:
Ag+ (aq) + Cl− (aq) → AgCl (s)
This net ionic equation demonstrates the formation of the insoluble salt, AgCl, which precipitates out of the solution. The equation is balanced in terms of both mass and charge as required by the law of conservation of mass and charge.
