Which of the following is an example of a double displacement reaction?

The reaction between silver nitrate and sodium chloride to form silver chloride and sodium nitrate is an example of a double displacement reaction. This reaction involves the exchange of ions between the two aqueous reactants: the silver ions (Ag+) pair with chloride ions (Cl-) and sodium ions (Na+) pair with nitrate ions (NO3-). A key feature of this specific reaction is the formation of a white precipitate of silver chloride (AgCl), which is insoluble in water. The remaining product, sodium nitrate, stays dissolved in the solution, making this a classic example of a precipitation reaction.
