Final answer:
The products of any double-replacement reaction are two different compounds, with one of the products usually being a solid precipitate, a gas, or a molecular compound such as water.
Step-by-step explanation:
A double-replacement reaction occurs when parts of two ionic compounds exchange places, resulting in the formation of two new compounds. The general form of a double-replacement reaction is: AB + CD → AD + CB. In this reaction, the positively-charged cations A and C switch places, as well as the negatively-charged anions B and D.
The products of any double-replacement reaction are two different compounds. One of the products is usually a solid precipitate, a gas, or a molecular compound such as water. For example, if AB and CD are aqueous solutions of sodium chloride and silver nitrate, respectively, the double-replacement reaction will yield sodium nitrate (NaNO3) and silver chloride (AgCl), with AgCl being the solid precipitate.
