The bonds formed in the product compounds are the same type of bonds as seen in the reactant molecules. A double displacement reaction is a type of chemical reaction where two compounds react, and positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products Double displacement reactions typically result in the formation of a product that is a precipitate. Examples of Double Displacement Reactions Precipitation Reactions. 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. Double Displacement Reaction. The ion SO4 does not have a subscript (4 is not the subscript because this is included in the ion). She has taught science courses at the high school, college, and graduate levels. The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other.

However, the product may be a precipitate, gas, or a liquid. The general form of a double-replacement (also called double-displacement) reaction is: (11.9.1) AB + CD → AD + BC In this reaction, A and C are positively-charged cations, while B and D are negatively-charged anions. Barium chloride solution can thus be used to test for sulfate ions. On the other hand, when elements of two compounds are interchanged between each other, the reaction is a double displacement reaction. The resulting products are sodium chloride and water. NaOH (aq) + HCl (aq) ➜ NaCl (aq) + H2O (aq). For example, consider the possible double-replacement reaction between Na 2 SO 4 and SrCl 2.The solubility rules say that all ionic sodium compounds are soluble and all ionic chloride compounds are soluble except for Ag +, Hg 2 2+, and Pb 2+, which are not being considered here.Therefore, Na 2 SO 4 and SrCl 2 are both soluble. A precipitation reaction occurs between two aqueous ionic compounds to form a new insoluble ionic compound. The key to identifying the reaction as double displacement is to look at the atoms of the anions and compare them on both sides of the reaction.

Predicting and balancing neutralization and precipitation reactions. A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. A double displacement reaction is one in which two reactants produce react to form two or more new products. Similarly, in this type of reaction, anions and cations of two reacting compounds exchange their places after the reaction happens. People switch to a new dancing partner after some time during the party. To summarize the concept of a double displacement reaction briefly, it can be said that two compounds exchange their component elements to form two new compounds. This usually creates a solution of a salt and water. The general form of a double-replacement (also called double-displacement) reaction is: $\ce{AB} + \ce{CD} \rightarrow \ce{AD} + \ce{BC}$ Solubility rules are used to predict whether some double-replacement reactions will occur.
