Dissolve about 2 g of CuSO4.5H;O in about 20 mL of tap water in 100 mL beaker. Then add 6 g zinc granules. Leave the mixture undisturbed on the demonstration bench for about 2 hours. Record your observations: Write a chemical equation for the chemical reaction that occurred: Cu'- ions were whereas Zn atoms were What type of chemical reaction is this? Experiment 4 (b): Add about 3 mL of an aqueous solution of iron(II) sulfate to a test tube. Then add few drops of potassium thiocyanate to the solution of iron(III) sulfate. Shake the test tube. Record your observations: Write a chemical equation for the chemical reaction that occurred: Еxpertment 4 (e): Place about 3 ml. of hydrochloric acid in a test tube. Then add a strip of magnesium to it. At the end of the reaction, touch the test tube at the bottom. Record your observations: Write a chemical equation for the chemical reaction that occurred: What type of reaction is this? In terms of heat exchange, how can you describe this reaction? Experiment 4 (d): Dissolve a spatula-tip of calcium acetate in about 5 mL of tap water in a test tube. Then add to this solution a few drops of an aqueous solution of sodium oxalate. Shake the mixture and then wait for about 3 minules. Record your observations: Write a chemical equation for the chemical reaction that occurred: What type of reaction is this? Еxperiment 4 (e): Dissolve half a spatula-tip of sodium bicarbonate in 5 ml. tap water in a test tube. Then add few drops of a solution of sulfuric acid Record your observations: Write a chemical equation for the chemical reaction that occurred:
