Write a balanced net ionic equation for the following reaction. Explain how you arrived at this answer. What did you cancel out?
yaroslaw [1]

 The net ionic equation  is


Ag⁺(aq)  +Cl⁻(aq) →  AgCl(s)


Explanation


AgNO₃ (aq)  + KCl (aq)→ AgCl(s) +KNO₃(aq)



from above  molecular equation break  all  soluble electrolyte  into ions


Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) →   AgCl (s) + K⁺(aq) + No₃⁻(aq)



cancel the spectator  ions  in both side  of  equation =K⁺  and NO₃⁻  ions



The net  ionic equation is therefore


= Ag⁺(aq)  + Cl⁻(aq) →    AgCl(s)
