Single displacement reaction is a chemical reaction where one reactant is exchanged for one ion of a second reactant.
Example: Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
A typical characteristic of a single-replacement reaction is that there is one element as a reactant and another element as a product.
