Reactivity Series Definition in Chemistry
The reactivity series is also known as the activity series of metals. The series is based on empirical data on the ability of a metal to displace hydrogen gas from water and acid. Practical applications of the series are prediction of double displacement reactions involving two metals and the extraction of metals from their ores.
