Double Displacement Reaction

What is the point of Chemistry?

A double displacement reaction involves the exchange of cations between two ionic compounds. Usually, this reaction is presented with the equation: AB + CD  -> AD + CB where A, B, C, and D are elements of the periodic table. Often, double displacement reactions result in the formation of a precipitate. On the other hand, a double displacement reaction can also result of an unstable compound, which then decomposes into gas or water. Another type of double displacement reaction is the mixture between a base and an acid. This usually results to salt and water.

However, there is also the the factor of appearance. The question is: How can you tell if a double displacement reaction has occurred? How can you predict the products of a double displacement reaction? The purpose is to help understand the various types of double displacement reactions and how they are in reality.
