There are three main types of reactions that occur in aqueous solutions. These are precipitation reactions, acid-base reactions and redox reactions.
Precipitation and acid-base reactions are sometimes known as ion exchange reactions. Ion exchange reactions also include gas forming reactions. Ion exchange reactions are a type of reaction where the positive ions exchange their respective negative ions due to a driving force.
A precipitate is formed when ions in solution react with each other to form an insoluble product. Solubility rules help to identify the precipitate that has been formed.
An acid-base reaction is one in which an acid reacts with a base to form a salt and water.
A redox reaction is one in which electrons are transferred from one substance to another.
