reactivity series experiment practical

> Reaction with CuSO4 solution: (a) This will show displacement reaction. The reactivity series In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. Hence, the reactivity order is Al > Zn. 21. What is the colour of Al2(SO4)3 solution? (a) add Zn in test tube A and B (a) Fe displaces copper ions. The reactivity series helps us to predict the capability of a metal to displace another metal during a displacement reaction. 28. What is the colour of copper sulphate solution? (c) As per reactivity series. (c) it is kept undisturbed Hypothesis. > A more reactive metal will displace (take the place of) a less reactive metal in a metal salt solution. (a) Test tube with CuSO4 solution (b) R is displaced by P There is an interactive version to use with the class. 2. (d) rough and granular. The series is based on empirical data on the ability of a metal to displace hydrogen gas from water and acid. Wash the test tubes after every set of observations of interaction of a particular metal with the four salt solution. Answer: On observing the strip the next day, it was noticed that To determine the position of Element X in the reactivity series. Complete the given chemical equation Fe(s) + CuSO4(aq) —> (c) I and II (d) III and IV. Conclusion: Al, Zn and Fe metals are more reactive than Cu. (b) hard and flaky. Note: When metals react with nitric acid they do not release hydrogen gas (except magnesium and manganese) because nitric acid acts as a strong oxidizing agent. Why did the colour of copper (II) sulphate solution, change, when zinc metal was dipped in it? To identify the solutions, 4. Question 1: (a) II, III (b) I, III This is a two-lesson bundle that guides students through planning an investigation into the reactivity of different metals and then carrying out their experiment. Al > Zn > Fe > Cu. 18. Overview: The students will develop their own activity series of metals based on lab results. (a) white (a) The freshly deposited copper is soft and dull. (d) Cu is the least reactive metal and can be displaced by all the metals given. (Acids contain H+ ions). (d) Copper sulphate is blue and ferrous sulphate is green in colour. A + BX —> AX + B (d) it is heated. Al2(SO4)3 solution in each test tube. 16. Answer: Question 4: With a marker label them as A, B, C and D. The four students A, B, C and D recorded their observations in the form of a table as given below. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. 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. (b) Copper salt is blue in colour and aluminium salts are colourless. These displacement reactions are used to establish an order of reactivity down Group 17 of the periodic table. ACTIVITY SERIES LAB (MICROSCALE) Purpose: to study the chemical activity of ... the six reagents you will be using in this part of the experiment: KNO 3, Mg(NO 3) 2, Zn(NO 3) 2, CuSO 4, AgNO 3, and distilled water. 2. Reactivity series and displacement reactions A worksheet that tests students confidence with the reactivity series by asking them to work with some displacement reaction equations. 2I– (aq) + Cl2 (aq) —> 2l– (aq) + I2 (solvated) (d) Copper is more reactive than Ag. The blue colour of the crystals is due to these five water molecules. 32. 3. 17. (a) Q displaces P Answer: Students work in (c) smooth and shining Answer: 2. The most reactive element is placed at the top and the least reactive at the bottom. 5. The arrangement of metals in the decreasing order of their reactivity is called activity series of metals. Question 5: What metal is the least reactive? The resource is set out as teachers' notes followed by the students' page which presents the task to be investigated. The colour of the solution and that of the coating would respectively be Which one is not observed when aluminium is added to a solution of copper sulphate? 22. Record your observations. No reaction will take place, as Fe metal is less reactive than Zn. He added 10 mL of freshly prepared ferrous sulphate solution to each test tube as shown 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 Answer: On adding iron strip in copper sulphate solution, the reaction takes long time, to make it happen fast we can: (c) I, II, III (d) II, III, IV. > If a less reactive metal is added to a more reactive metal salt solution then there will be no reaction. (d) Iron is less reactive than Zn. Zinc and magnesium. Reactivity series of metals and nonmetals are the lists, in which we arrange them in the decreasing order of their chemical activity. Here, in the above reaction it is S042- ion. 2. (a) blue (b) brown To show that zinc is more reactive than copper, the correct procedure is to (d) All tests will help in identifying the solutions. From CBSE Science practical to Lab manual, project work, important questions and CBSE lab kit manual, all the information is given in the elaborated form further in this page for Chapter 4 Reactivity Series students. Do not touch any chemical. Question 10: Theory: The reaction rate or rate of reaction for a reactant or product in a particular reaction is intuitively defined as how fast a reaction takes place. Answer: Question 5: (d) Zinc and alufninium being more reactive will replace iron from iron sulphate. It can be done as a demonstration or as a class experiment. Question 6: 10. Answer: BX is a salt of metal B. 24. (d) copper sulphate solution only changed. 29. Non-Metal Displacement Reactions Question 7: Al2(SO4)3 solution is colourless. 30. Answer: (b) blue to colourless In these reactions the metal atoms lose an electron to become a metal ion (being oxidised). 23. Give reason. 22. (b) it is shaken > Non-Metals: The atoms of non-metals gains or shares electrons to form negative ions called anions, the atoms of non-metals if readily gains electrons it is said to be more reactive. Answer: Question 8: > Reaction with ZnSO4 solution: Fe(s) + CuSO4(aq) —> FeSO4(aq) + Cu(s). 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. 3. (b) It shows thermite reaction and heat is evolved. (ii) Arrange Zn, Fe, Cu and Al metals in the decreasing order of reactivity based on the above result. To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions: Arrange Zn, Fe, Cu and A1 metals in the decreasing order of reactivity based on the above result. Dip small, clean pieces of Al, Zn, Fe and Cu metal in test tube A, B, C and D respectively. 4. (d) reddish-brown to light green. Log in. each of four test tubes. Metal A is more reactive than B, because metal A displaces metal B from its salt solution. I will react each metal (Mg, Fe and Cu) with the salt solutions of Mg, Fe and Cu. 5.
