Question 3: Which is the most reactive metal?Īccording to the reactivity series of metals, Potassium (K) is the highly reactive metal.The text below has been excerpted from Compound Chemistry Student handout: Reactivity Series of Metals (PDF) This graphic places a selection of common metals into order of reactivity, as well as showing their reactions with air, water and steam. This implies that the most reactive metals are at the top while the least reactive metals at the bottom. Reactivity series shows a list of metals arranged based on their tendencies to react from highest to lowest order. Question 2: What does a reactivity series show? The arrangement of metals in a series of decreasing order of their tendencies to react is called the Reactivity Series of metal. Question 1: What is the reactivity series of metals? Words/Mnemonic used to Remember the SeriesįAQs based on the Reactivity Series of Metals Here we have uses the sentence “Please send charlie’s monkeys and zebras in lead & hydrogen cages in mountains securely guarded by Plato.” The first letter of each word represents a metal of the reactivity in the order from highest to lowest as: Symbol The basic strategy for learning the reactivity series is to group these elements into meaningful groups and then use a mnemonic for each group. the reaction is given below:ĢNa(s) + 2HCl (dilute) → 2NaCl (aq) + H 2(g) Tricks to Remember Reactivity Series of Metals Sodium metal has a tendency to displace hydrogen from hydrogen chloride (HCl) to form sodium chloride and liberate hydrogen gas.Metal + dilute acid → Salt + Hydrogen gas Reaction with Acid and bases: Metals, displace hydrogen from its dilute acids which are more reactive than hydrogen, and form respective metal salts and hydrogen gas.For example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below. Reaction Between Metals and Water: Calcium and the metals that are more reactive than calcium in the reactivity series can react with cold water to form the corresponding hydroxide while liberating hydrogen gas.For example, the result we get out of the reactions between metals and acids, metals and water, and single displacement reactions between metals can be predicted. The reactivity series provides the study of properties and reactivities of the metals, Apart from this reactivity series also provides several other important applications. Highly unreactive May react with some of the strong oxidizing acids May react with some strong oxidizing acids Reacts very slowly with cold water, whereas quickly in boiling water, and very strongly with acids. The Reactivity series of some of the most common metals, arranged in descending order of reactivity: Long Tabular Form of the Reactivity Series Higher ranking metals require greater amounts of energy for their isolation from ores and other compounds.On reaction with dilute HCl or dilute H 2SO 4, all metals that are found above hydrogen in the activity series liberate H 2 gas.The tendency to reduce the metals becomes weaker while traversing down the series.The electro-positivity (tendency to lose electrons) of the elements gets reduced while moving down the reactivity series of metals.These metals can get tarnished or corrode very easily. The reducing tendency of metals at the top of the table has high, that is why they are easily oxidized.Arithmetic Progression - Common difference and Nth term | Class 10 Maths.Area of a Triangle - Coordinate Geometry | Class 10 Maths.Chemical Indicators - Definition, Types, Examples.Class 10 RD Sharma Solutions- Chapter 2 Polynomials - Exercise 2.1 | Set 2.Euclid's Division Algorithm - Real Numbers | Class 10 Maths.Electric Potential and Potential Difference.Step deviation Method for Finding the Mean with Examples.
