When both products are soluble, a double replacement equation will not produce a reaction.
We use the (s) symbol for solid because salt is an insoluble substance that will not dissolve in water. The silver, fluoride, potassium, and chloride ions would have effectively moved to a new location if there had been no precipitate formation, but they would still be floating around as ions. In this scenario no reaction happens.
A double replacement reaction occurs when two ionic compounds swap ions to form two new ionic compounds. The following response is an example of this kind: AB + CD AD + CB.
