The metals which are placed above in the series can be extracted by electrolysis. Thus, metals placed at the top of the reactivity series can remove the metals which are present at the bottom of the series from their salts. The metal which is more reactive than other metals can remove less reactive metal from its salt. Metals present in the reactivity series above hydrogen can remove hydrogen ions from dilute HCl or Dilute sulphuric acid. Thus, potassium is the strongest reducing agent.Īs we go down the reactivity series, the ability of metals to remove hydrogen from hydrides decreases. The reducing power of metals decreases as we go down the series. The electropositive character of metals decreases as we go down the series. Metals present at the top of the reactivity series are highly electropositive metals. May react with some of the strong oxidizing acids May react with some strong oxidizing acids Reacts with acids very poor reaction with steam Or less commonly other alkali metals, hydrogen or calcium in the Kroll process Pyrometallurgical extraction using magnesium, In boiling water, and very vigorously with acids. Reacts very slowly with cold water, but rapidly Here is the tabular format of the same.Įlectrolysis (a.k.a. Here metals are segregated in terms of their reaction with cold water, hot water, acid, and steam and reaction with concentrated mineral acids. The reactivity of the metals is given below in another tabular format where it has been mentioned along with its ions. Hydrogen is a non-metal but still, it has been included in the reactivity series as it helps in the comparison of reactivity of metals. While metals such as zinc, aluminium, magnesium, calcium, etc. This is the reason why platinum and gold don’t get corrode easily and don’t form oxides. Metals from copper to platinum are highly unreactive and don’t react with any other substance in normal conditions. While metals from magnesium to lead can react with acids. Metals from potassium to calcium are highly reactive and even react with water.
