Examine the reactants of the incomplete double displacement reaction.

AgNO3 + NaCl → _[blank].

What are the products of the double displacement reaction?

AgCINaNO3

Ag + Cl + Na + NO3

AgCINa + NO3

AgCl + NaNO3

AgCl + NaNO₃

Explanation: The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction. In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts. In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate. Therefore, the complete reaction is given by;

AgNO3 + NaCl → AgCl + NaNO₃

But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
