Students will investigate competition reactions of metals and determine a reactivity series of the four metals used. What is the colour of iron sulphate solution? What is the activity series of metals? This observational exercise allows the metals to be placed in series depending on their reactivity. Fe is unable to displace Zn from its salt solution, whereas Zn is able to displace Fe from its salt solution, therefore Zn is more reactive than Fe. 30. > The arrangement of metals in decreasing order of their reactivity is called reactivity series or activity series of metals. Two metals which can displace iron from its solution are: Sourabh Das 25/01/2014 Reactivity Series Experiment Pre-Lab Answers: 1. calcium + water ==> calcium hydroxide + hydrogen. Materials Required The most reactive metal displaces the less reactive metal from its salt solution. Four students A, B, C and D noted the initial colour of the solutions in test tubes I. II, III and IV. He added 10 mL of freshly prepared ferrous sulphate solution to each test tube as shown below: The reactivity series of metals is Take FeSO4 (aq) solution in each test tube. I will react each metal (Mg, Fe and Cu) with the salt solutions of Mg, Fe and Cu. 19. Answer: No reaction will take place, as Fe metal is less reactive than Zn. Aluminium sulphate and copper sulphate solutions were taken in two test tubes I and II respectively. Question 11: (c) heat zinc and copper strips. 8. As Al, Zn and Fe can displace Cu from its salt solution hence, all three are more reactive than Cu. 12. 1. Answer: It can be done as a demonstration or as a class experiment. 18. When a more reactive metal displaces the less reactive metal from its salt solution, it is called displacement reaction. > Reactivity series: The arrangement of metals in decreasing order of their reactivity is called reactivity series. 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 Questions based on Procedural and Manipulative Skills Hence, the reactivity order is Al > Zn.

A few pieces of iron filings were then added to both the solutions. Answer: Answer: Dip small, clean pieces of aluminium, zinc, iron and copper metals in test tube A, B, C and D respectively. The blue colour of the crystals is due to these five water molecules. (a) Fe + FeSO4 Copper is less reactive than iron and cannot displace iron from iron sulphate solution and there is no colour change. It is because Fe does not react with FeSO4 solution. Practical Based Questions PBQs based on every experiment with their answers, covering Previous Years’ Questions, are provided experiments for complete coverage of concepts Web support By performing the experiments, students will know the concept in a better way as they can now view the changes happening in front of their eyes. As Zn and Al can displace Fe from its salt solution hence, Zn and A1 are more reactive than Fe but Cu is less reactive than Fe. (a) all the four solutions changed. 10.
