reactivity series experiment practical

(c) light green to colourless When a few crystals of copper sulphate are dissolved The colour of the coating obtained on a zinc rod on dipping in aqueous copper sulphate solution will be This is a reliable technique used, because aluminium is actually a reactive metal but due to the protective coating of aluminium oxide on it, the results may show that aluminium’s reactivity rate is slow. Name the least reactive metal among the following: Fe, Zn, Al. 12. Answer: (c) heat the container of reactants There is an interactive version to use with the class. For any questions pertaining to CBSE Class 10 Science Practicals Reactivity Series Material, feel free to leave queries in the comments section. Here we have given all the necessary details that a Chapter 4 Reactivity Series student should know about CBSE Class 10 Lab Manual. Question 2: 10. 3. Question 8: (d) Copper is more reactive than Ag. 29. When a more reactive metal displaces the less reactive metal from its salt solution, it is called displacement reaction. Reactions of metals with water and acids can be used to arrange metal elements in (d) reddish-brown to light green. (a) add Zn in test tube A and B (b) it is shaken (a) yellow and Zn (b) green and Fe (c) red and Sn (d) blue and Ag. With a marker label them as A, B, C and D. Answer: Some metals are more reactive than others. (c) II and III (d) III and IV. The iron nail reacts with copper sulphate displace copper and form iron sulphate . What is your observation when copper is added in iron (II) sulphate solution? Answer: 2. 5. Question 5: > The arrangement of metals in decreasing order of their reactivity is called reactivity series or activity series of metals. (b) It shows thermite reaction and heat is evolved. Al > Zn > Fe > Cu. Green iron II sulphate is formed. 27. The series is based on empirical data on the ability of a metal to displace hydrogen gas from water and acid. The right pair of metals forming the precipitates is Do not touch any chemical. What is the activity series of metals? > For example, in a given chemical reaction: 11. (c) blue (d) brown. Iron metal reacts with copper sulphate solution to displace copper and form iron sulphate that is green in colour. > Speed of reaction: We can calculate the speed of reaction of metals by allowing them to react with water at room temperature and collect the hydrogen gas obtained. Fe(s) + CuSO4(aq) —> FeSO4(aq) + Cu(s). These elements are below hydrogen so they do not react with acids. After 10 minutes it was observed that the colourless solution turned to a coloured solution and a shiny metal deposition appears. The atoms react due to its tendency to lose, gain or share electrons. 21. They recorded their observations in the form of table given below: Which student noted the colour change in all the four test tubes correctly? The decreasing order of reactivity for these metals follow the order: Observe the changes carefully as few reactions may occur slowly. (d) Cu is the least reactive metal and can be displaced by all the metals given. When you keep aluminium strip in FeSO4 solution, what change is seen? 23. Answer: (a) This will show displacement reaction. (a) Fe displaces copper ions. A student took four test tubes containing solutions of different colours marked I, II, III, and IV as shown below. Fe is the least reactive metal among Fe, Zn, and AT. (b) Cu is displaced by Zn which is brown in colour. (ii) Salt solution FeSO4. > Reaction with ZnSO4 solution: 18. Al2(SO4)3 solution in each test tube. 14. (d) all the above are correct. (b) prepare copper sulphate solution and dip a copper strip in it. (b) Zinc is most active metal followed by copper and then iron.

(c) Cu is less reactive than Zn. (i) To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions: Metal + Acid —> Metal salt + Hydrogen. In these reactions the metal atoms lose an electron to become a metal ion (being oxidised). II. 2Na (s) + 2H 2 O (l) ==> 2NaOH (aq) + H2 (g) You can write similar equation for lithium and potassium (Li/K instead of Na) and. Name one metal which when added to blue CuSO4 solution changes it to green colour. The Reactivity Series of Metals, but some examples are given below. It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores (d) add dilute nitric acid on both the strips. These metals cannot displace hydrogen from acids and water.You can also download. (c) I and II (d) III and IV. (c) Equilibrium is seen. Therefore, the reactivity of a metal is related to its ability to form positive ions. As you can see these metals (excluding carbon, as carbon is used for the reduction of metal from metal oxide ore, all metals below carbon are reduced by it) are above hydrogen in the reactivity series so they react with acids and displace hydrogen gas.
