In the following experiments wash the test tube and the measuring cylinder before each use. You are provided with Solution A (a) Place three drops of solution A on a white tile and add one drop of iodine solution. Record your observation (b) Put 10cm³ of solution A in a beaker and add a few drops of dilute tetraoxosulphate (vi) acid (H\(_2\)SO\(_4\),) in a test tube and boil fora few minutes. Then add a few drops of sodium hydroxide solution and allów the mixture to cool. Divide the mixture into two equal portions
