A double replacement reaction will occur if a formation of a precipitate , gas or water takes place. Select two compounds above and this calculator will predict whether or not the reaction will occur in water.This is simply based on the solubility chart of inorganic compounds. In double replacement, both reactants are compounds, each with a cation part and an anion part.


Definition and examples of double replacement reactions. Key Takeaways: Double Replacement Reaction A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products. Diatomic elements do not count; they are included in the single replacement category. A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions.

A double displacement reaction is also called a double replacement reaction, salt metathesis reaction, or double decomposition. This type of reaction is also called metasynthesis or double replacement.

The reaction occurs most often between ionic compounds, although technically the bonds formed between the chemical species may be either ionic or covalent in nature.

Predicting and balancing neutralization and precipitation reactions. Typically, you will be given the left-hand (reactant side) and asked to provide the products to the reaction. A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. Anions and cations of compounds change their placement to react and form altogether different compounds. The general form of a double-replacement (also called double-displacement) reaction is: \[\ce{AB} + \ce{CD} \rightarrow \ce{AD} + \ce{BC}\] Double-Replacement Reactions. The standard representation of this type of equation is as given below: UV + XY UY + XV This equation can be represented in terms of the ionic charges as follows:
