MATERIALS REQUIRED Two test tubes, two iron nails, measuring cylinder (50 mL), laboratory stand with clamp, test tube stand, thread, a piece of sand paper, single bored cork, copper sulphate, distilled water, and dil. Sulphuric acid, PROCEDURE 1. Take two iron nails and clean them with a sand paper. Take 20 mL of distilled water in a clean test tube and dissolve 1.0 g of copper sulphate in it.
Add 2 or 3 drops of dil. Sulphuric acid to it to check hydrolysis of CuSO4 in water. Label this test tube as A. Transfer about 10 mL of copper sulphate solution from tube A to another clean test tube. Label this test tube as B. Tie one iron nail with a thread and immerse it carefully in copper sulphate solution in test tube B through a bored cork as shown in the Fig 1.1(a) for about 15 minutes Fig.
Keep the another iron nail separately for comparison afterwards. After 15 minutes take out the iron nail from the copper sulphate solution. Compare the intensity of blue colour of copper sulphate solution before and after the experiment in tubes A and B, and also compare the colour of iron nail dipped in copper sulphate solution with the one kept separately Fig. 1.1(b) and (c). Record your observations. RESULTS AND DISCUSSION Infer from your observations about the changes in colours of copper sulphate solution and iron nail. Discuss the reason(s).
PRECAUTIONS. The iron nails must be cleaned properly by using sand paper before dipping them in copper sulphate solution. QUESTIONS. Why does the colour of copper sulphate solution change, when an iron nail is dipped in it?. How would you devise the procedure to show that Mg Fe Cu in reactivity series?.
What is the basic principle involved in this experiment?. Why does the following reaction takes place?. Why does a red litmus paper changes its colour when dipped in soap solution?
Explain your observation. Why is it advised to add common salt while preparing the soap?. Can we use Na2CO3 instead of NaOH?. Was heat evolved or absorbed when sodium hydroxide was added to oil?. What is the chemical reaction involved in the manufacture of soap?. Can you devise a method to separate glycerine from the reaction mixture?
