Double replacement reaction. This chemistry video tutorial explains how to identify the products of a double replacement reaction from a sentence or word problem. This trick works with double replacement reactions also known as double displacement reactions. In double replacement both reactants are compounds each with a cation part and an anion part.
The general form of a double-replacement also called double-displacement reaction is. 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. Select two compounds above and this calculator will predict whether or not the reaction will occur in water.
The figure below clearly illustrates how this swap takes place. Imagine a hypothetical situation where a kid who loves ice. A double-replacement reaction occurs when parts of two ionic compounds are exchanged making two new compounds.
In a double replacement reaction two compounds swap atoms forming two different compounds. In single replacement reactions one element replaces another in a chemical compound. Usually one of the products forms a precipitate.
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. Like single replacement reactions metals always replace metals and nonmetals always replace nonmetals. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.
Double-Replacement 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. For example consider the reaction between aqueous leadII nitrate with aqueous potassium bromide as shown below. Double replacement reaction occurs when the cations and anions of two ionic compounds are exchanged.
