Definition & Meaning
A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. This process can be represented by the general equation: A + BC → AC + B. In this equation, element A displaces element B from the compound BC, forming a new compound AC. These reactions are essential in various chemical processes, including those used in industries and laboratories.
Single replacement reactions typically occur between a more reactive element and a less reactive element. For example, if zinc (Zn) is placed in a solution of copper sulfate (CuSO4), zinc will replace copper due to its higher reactivity, resulting in the formation of zinc sulfate (ZnSO4) and copper (Cu).
