. Give an example of a double displacement reaction other than the one given in Activity 1.10.

Reaction A double displacement reaction can be seen between sodium chloride (NaCl) and silver nitrate (AgNO₃₎. Due to the production of a white silver chloride precipitate, positive and negative ions exchange positions during the reaction.

The chemical is explained below :

Ag⁺ + NO₃^– + Na⁺ + Cl^– → AgCl + Na⁺ + NO₃^–
