What is the name for a reaction in which two compounds exchange ions to form two new compounds?

Explanation:
In a double-replacement reaction, ions in two compounds swap partners to form two new compounds. This ion-exchange pattern AB + CD → AD + CB is common and can lead to a precipitate, water, or a gas, signaling that a reaction has occurred. This distinguishes it from single-replacement, where only one element swaps places with another compound; synthesis, where two substances combine into one product; and decomposition, where one compound breaks into simpler substances. Recognizing the swap of partners helps you predict the outcome and the possible products.
