What is the Reactivity Series?

The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending society of their reactivities.

The information provided past the reactivity series can exist used to predict whether a metallic tin can readapt some other in a single displacement reaction. It can also be used to obtain information on the reactivity of metals towards water and acids.

A chart of the reactivity serial of common metals is provided beneath.

Metals tend to readily lose electrons and form cations. Most of them react with atmospheric oxygen to form metal oxides. However, unlike metals accept different reactivities towards oxygen (unreactive metals such as gold and platinum do not readily form oxides when exposed to air).

Salient Features

  • The metals at the acme of the reactivity series are powerful reducing agents since they are easily oxidized. These metals tarnish/corrode very hands.
  • The reducing power of the metals grows weaker while traversing down the series.
  • The electro positivity of the elements also reduces while moving down the reactivity series of metals.
  • All metals that are found in a higher place hydrogen in the activeness series liberate H2
    gas upon reacting with dilute HCl or dilute H2SO4.
  • Metals that are placed higher on the reactivity series accept the ability to readapt metals that are placed lower from their salt solutions.
  • Higher ranking metals require greater amounts of energy for their isolation from ores and other compounds.

Another important feature of the activeness serial is that while travelling down the series, the electron-donating power of the metals reduces.

Despite existence a not-metal, hydrogen is often included in the reactivity series since information technology helps compare the reactivities of the metals. The metals placed above hydrogen in the series can displace it from acids such as HCl and H2SO4
(since they are more reactive).

Important uses of Reactivity Series

Autonomously from providing insight into the backdrop and reactivities of the metals, the reactivity serial has several other important applications. For example, the outcome of the reactions between metals and water, metals and acids, and single displacement reactions between metals can exist predicted with the assistance of the action serial.

Reaction Between Metals and Water

Calcium and the metals that are more than reactive than calcium in the reactivity serial can react with cold water to grade the corresponding hydroxide while liberating hydrogen gas. For example, the reaction between potassium and water yields potassium hydroxide and H2
gas, as described by the chemical equation provided beneath.

2K + 2H2O → 2KOH + H2

Therefore, the reactivity series of metals can be used to predict the reactions betwixt metals and water.

Reaction Between Metals and Acids

Lead and the metals ranking above atomic number 82 on the activity series course salts when reacted with hydrochloric acid or sulphuric acid. These reactions too involve the liberation of hydrogen gas. The reaction between zinc and sulphuric acid is an example of such a reaction. Here, zinc sulfate and H2
gas are formed as products. The chemical equation is:

Zn + HtwoSo4
→ ZnSO4
+ H2

Thus, the reactions between metals and some acids can be predicted with the help of the reactivity series.

Single Displacement Reactions Betwixt Metals

The ions of low ranking metals are readily reduced by high ranking metals on the reactivity serial. Therefore, low ranking metals are hands displaced by high ranking metals in the single displacement reactions between them.

A peachy example of such a reaction is the displacement of copper from copper sulphate by zinc. The chemical equation for this reaction is given by:

Zn (s) + CuSO4
(aq) → ZnSO4
(aq) + Cu (s)

This concept has several practical applications in the extraction of metals. For example, titanium is extracted from titanium tetrachloride via a single deportation reaction with magnesium. Thus, the reactivity serial of metals can also exist used to predict the issue of unmarried deportation reactions.

Frequently Asked Questions

What does a reactivity series bear witness?

The metal reactivity serial is a list of metals arranged in the order of their decreasing activities. The metals at the top of the series (K, Na, Ca, Mg and Al) are so reactive that they are never plant in nature as free elements. It is difficult to dissever them from their compounds and extract. The metals at the bottom of the activity series are the to the lowest degree reactive. Some of these metals are found in the world’s crust in their complimentary country. For example, Gold, Platinum is constitute in gratuitous country. So, it becomes comparatively easier to extract such to the lowest degree reactive metals

Which metal is the least reactive?

Platinum is the to the lowest degree reactive metal. Information technology has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum.

What is metal reactivity?

Reactivity series is a list of metals bundled in decreasing society of their reactivity. Most reactive metals are at the meridian while the least reactive metals at the lesser. For whatever ii metals in the series, the metal placed higher in the series can displace lower metals from their table salt solution.

Which is the most reactive metal?

alkali metal are most reactive metals. Down the reactivity increases. Francium is most reactive element in periodic table. However, francium is artificial or merely few quantities accept produced right now, then later the francium, cesium is near reactive metal.

Are non-metals Reactive or non-reactive?

Not-metal properties have a relatively low humid point, and other non-metals are gases. Likewise, non-metals are poor heat conductors, and solid not-metals are dull and breakable. Many non-metals are strongly reactive, while others are in no way reactive. It depends on the number of electrons in the outer amount of energy.

What is the reactivity series of metal?

The reactivity series of metals refers to the array of metals in the descending club of their reactivities. Information technology is also known as the activity series of metals.

What does the reactivity series of metals depend on?

The reactivity series of metals depends on the reactivity of metals which is dependent on the atomic radius, nuclear accuse, sublevel electrons organization and shielding effect.

How is the reactivity series of metals originated?

The reactivity of metal originated from the reactivity of metals. In the action series of metals more than reactive metal is placed on the top of the serial while a less reactive metal is placed at the bottom of the serial.

What is the significance of the reactivity series of metal?

The reactivity series of metals is the array of metals in the descending social club of their reactivities. It helps in predicting if a metal tin can readapt some other metal in a deportation reaction.

Why is hydrogen placed in the reactivity series of metal?

Hydrogen is a office of the reactivity serial of metals because like metals it as well loses electrons to form a positive ion.
