When a silver nitrate solution is mixed with sodium chloride, silver chloride precipitates are formed in the solution of sodium nitrate solution. It is a double displacement reaction because silver nitrate and sodium chloride exchange their components to form new product including silver chloride and sodium nitrate.
AgNO3 ------ > Ag+1 + NO3-1
NaCl ------ > Na+1 + Cl-1
The net ionic equation for the reaction is;
AgNO3(aq) + NaCl (aq) ------> AgCl (s) + NaNO3 (aq)
AgNO3 ------ > Ag+1 + NO3-1
NaCl ------ > Na+1 + Cl-1
The net ionic equation for the reaction is;
AgNO3(aq) + NaCl (aq) ------> AgCl (s) + NaNO3 (aq)
