Double Displacement: Also known as double replacement; Usually occurs between two ionic compounds, which then in turn create two more ionic compounds. A chemical reaction in which an element replaces one element in a compound Explanation of single-replacement reaction double-replacement-reaction definition: Noun (plural double-replacement reactions) 1. What is Double Replacement Reaction? Looking for single-replacement reaction?

In double replacement, both reactants are compounds, each with a cation part and an anion part. Find out information about single-replacement reaction. Precipitation reactions produce one substance that is insoluble while acid-base reactions can produce soluble, liquid or gaseous reaction products. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds. Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate, and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. Describes the double-replacement reaction and gives examples. Example Double Replacement Reaction: Let's imagine ourselves going to a dance and having a dance partner. Solubility rules are used to predict whether some double-replacement reactions will occur. What is double displacement reaction? Diatomic elements do not count; they are included in the single replacement category. 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 precipitation or acid-base reaction in which the reactants ionize and either the positive or negative ions exchange places to produce two new substances. A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions. In double replacement reactions, the positive ions exchange negative ion partners.
