Reactivity Series of Metals

The video explores the chemical reactivity of metals, focusing on zinc, copper, potassium, calcium, lithium, magnesium, and sodium. It demonstrates experiments with cold water and hydrochloric acid to rank these metals by reactivity. The reactivity series is explained, highlighting how metals form positive ions. The video concludes with practical applications, such as explaining displacement reactions.
