In displacement reaction – Displacement reactions are those reactions in which more reactive metal displaces less reactive metal from its salt.
#Memorize activity series of metals series
When we move down the series the electron-donating capacity of metals decreases.
While metals from Zinc to Hg can be extracted by simply reducing their oxides, which is an inexpensive method. 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. The reducing ability of the metals grows weaker while traversing down the series.Metals from potassium to calcium are highly reactive and even react with water. These metals tarnish/corrode very easily. The metals at the top of the reactivity series are powerful reducing agents since they are easily oxidized. Long Tabular Form of the Reactivity Series Reactivity Series of Metals Ions Formed Lead Pb2+ Hydrogen H+ (Non-Metal, Reference for Comparison) Antimony Sb3+ Bismuth Bi3+ What is the effect of reactivity series on reducing power? What is the tabular form of the reactivity series? Therefore, the reactivity series of metals can be used to predict the reactions between metals and water. How can the reactivity series be used to predict chemical reactions?įor example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities.
It states like : Katrina ne car mangi Alto, zen, ferrari phirbhi kyu milli silver Audi. Most suitable and easy way to remember reactivity series (Hindi). How do you remember the spectrochemical series?
#Memorize activity series of metals how to
If you carry on with physics at uni you’ll find that you learn how to explain/understand quite a few things that just have to be limited to memorization in A-level chemistry. Yes it is mostly memorization at A level. Organic Chemistry: It shouldn’t surprise you that organic chemistry takes the No. Which is the correct order of reactivity series Mg Ca Na K?Īnswer: Option (b) K < Na < Ca < Mg is correct answer. A metal placed at tire top of the activity series would displace metal below it. A metal placed above hydrogen in the activity series will displace hydrogen from water or acids. The arrangement of metals in the vertical column in the order of decreasing reactivity is called reactivity series or activity series. What is reactivity series How does the reactivity series? I’d learn it just to stay on the safe side, when I did GCSEs we had to learn the reactivity series so I don’t know if it’s changed for you. It says you need to “explain” things by using the reactivity series but it doesn’t say you have to “recall” it. I LIKE HIS CAR’S SILVERY GATE.ĭo you need to Memorise the reactivity series?
