The general form of a double-displacement reaction is described by the following equation: When a portion of two ionic compounds is transferred, it creates two new components, which is known as a double displacement reaction. Another clue, if the states of matter are cited, is to look for aqueous reactants and the formation of one solid product (since the reaction typically generates a precipitate). On the other hand, when elements of two compounds are interchanged between each other, the reaction is a double displacement reaction.
