The net ionic equation is:
2Ag⁺(aq) + 2Cl⁻(aq) → 2AgCl(s)
The given equation is:
2AgNO₃ (aq) + CaCl₂ (aq) → 2AgCl(s) + Ca(NO₃)₂ (aq)
A double displacement reaction occurs when silver nitrate and calcium chloride are combined. Silver chloride precipitate and a calcium nitrate solution are the results of the reaction.
Break down all the soluble electrolytes, that are present in an aqueous form, into their respective ions:
2Ag⁺(aq) + 2NO³⁻(aq) + Ca²⁺(aq) + 2Cl⁻(aq) → 2AgCl(s) + Ca²⁺(aq)+ 2NO³⁻(aq)
Now remove all the spectator ions present in the equation. The spectator ions should be removed after comparing the reactant and product sides of the revised reaction. These dissolved ions are known as spectator ions if they exhibit the same form on both sides. No reaction occurs if everyone is a spectator ion.
Now write the net ionic equation:
2Ag⁺(aq) + 2Cl⁻(aq) → 2AgCl(s)
