Question
Give an example of a double displacement reaction.
Solution
In the reaction between silver nitrate and sodium chloride, silver swaps its nitrate ions for the chloride ions from sodium chloride, forming a silver chloride precipitate. The chemical reaction is:
\[\ce{AgNO3(aq) + NaCl(aq) -> AgCl(s) + NaNO3(aq)}\]
