The distillate collected in Step 5 is a mixture consisting of two layers. There is an aqueous layer and a layer containing impure 1-bromobutane.Step 7 Wash the impure 1-bromobutane with concentrated hydrochloric acid in the separating funnel. Remove the aqueous layer.Step 8 Add aqueous sodium hydrogencarbonate to the impure 1-bromobutane in the separating funnel.Step 9 Shake the mixture in the separating funnel and, from time to time, invert the funnel and open the tap.Step 10 - Collect the 1-bromobutane layer from Step 9 in a small conical flask.- Add anhydrous sodium sulfate and swirl the flask until the liquid becomes clear.Step 11 Decant the 1-bromobutane into a clean pear-shaped flask and redistil it. Measure the volume of 1-bromobutane produced Give the reasons for carrying out Steps 8, 9 and 10. (3)
