What Is A Double Displacement /replacement Reaction?
In double displacement reaction two compounds react to yield two products. Two compounds exchange their components to form two new compounds in a double displacement reaction. For example, sodium chloride and sulfuric acid react to form sodium sulfate and hydrochloric acid. The chemical equation for the reaction is; 2NaCl + H2SO4 ————> Na2SO4 + 2HCl Similarly, silver nitrate reacts with sodium chloride to yield silver chloride and sodium nitrate. AgNO3 + NaCl —> AgCl + NaNO3 The formation of common salt is also an example of double displacement reaction. NaOH + HCl ———- > NaCl + H2O The neutralization of an acid and base is also a double displacement reaction. 2KOH + H2SO4 —> K2SO4 + 2H2O Moreover, double displacement reaction is also known as double replacement reaction.
