Zn(s) + FeSO 4(aq) –→ ZnSO 4 (aq) + Fe(s) Reactivity Series of Metals for Class 10 The following equations shows the displacement of a less reactive element by a more reactive one:ĢAl(s) + 3ZnSO 4(aq) –→ Al 2(SO 4) 3 + 3Zn(s)ĢAl(s) + 3FeSO 4(aq) –→ Al 2(SO 4) 3 + 3Fe(s)ĢAl(s) + 3CuSO 4(aq) –→ Al 2(SO 4) 3 + 3Cu(s)įe(s) + CuSO 4(aq) –→ FeSO 4 (aq) + Cu(s) When compared to Cu, iron has the ability to displace copper from its salt solution, making it more reactive. Zinc is more reactive than iron and copper because it has the capacity to displace them from their salt solutions. Zinc is thus more reactive than copper.Īluminium is more reactive than zinc, iron, and copper because it has the ability to displace them from their salt solutions. Copper sulphate’s blue colour disappears, leaving a colourless zinc sulphate solution. Consider how zinc is displaced from copper sulphate when a small amount of zinc is immersed in a copper sulphate solution. These are known as displacement responses. In salt solution, a more reactive metal displaces a less reactive metal. Metals that lose electrons more readily produce positive ions. Reactivity Series Class 10Ĭhemical reagents react differently with different metals. The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. This series is also useful in explaining why certain metals are used for specific applications, such as corrosion resistance or electrical conductivity. In a displacement reaction, a more reactive metal can displace a less reactive metal from its compound. The reactivity series helps us understand and predict various chemical reactions, particularly in terms of displacement reactions. Gold (Au): Highly unreactive, does not react with acids. Silver (Ag): Generally does not react with acids. Hydrogen (H): Not a metal but included in the series can be displaced by metals higher in the series from acids.Ĭopper (Cu): Does not readily react with dilute acids. Lead (Pb): Reacts slowly with acids, mainly due to its oxide layer. Tin (Sn): Reacts with acids but slowly, and with a tendency to form a protective oxide layer. Iron (Fe): Less reactive than zinc, reacts with acids, but its reaction rate is slower. Zinc (Zn): Reacts with acids, releasing hydrogen gas. Magnesium (Mg): Reacts with steam and acids, but its reaction with water is slow.Īluminum (Al): Reacts with strong acids, but it forms a protective oxide layer on its surface, preventing further reaction. Sodium (Na): Reacts similarly to potassium, and also reacts with water to produce hydrogen gas and hydroxide ions.Ĭalcium (Ca): Reacts with water, albeit less vigorously than potassium and sodium. Potassium (K): Highly reactive metal, reacts vigorously with water. Here is the reactivity series in decreasing order of reactivity: This series helps to predict the behavior of metals when they come into contact with substances like acids or water. The reactivity series, also known as the activity series, is a list of metals and elements organized in order of their reactivity from the most reactive to the least reactive.
