ChemistryAnalysing substancesGCSEAQA Created by: tonisha_Created on: 30-10-22 16:08 Simple distillation is used for separating what? a liquid from a solid if we want to keep the liquid 1 of 27 Fractional distillation is used to separate? a mixture of liquids 2 of 27 SIMPLE DISTILLATION ------------------------------ Firstly pour the solution into a? flask 3 of 27 Then do what to the solution? heat it 4 of 27 Using a ? Bunsen burner 5 of 27 As the liquid is heated it will turn into what? a vapour 6 of 27 And will_____ up the _____ _____? will rise up the glass tube 7 of 27 Where will the vapour then pass into? a condenser 8 of 27 It will what in the condenser? cool and condense 9 of 27 What does condense mean? turn back into a liquid 10 of 27 And then will be ______ in a _____? be collected in a beaker 11 of 27 By the end what will be left in the flask and beaker? flask-dry crystals beaker-liquid 12 of 27 This method can be used to obtain what? pure water from sea water 13 of 27 FRACTIONAL DISTILLATION --------------------------- This method is used to separated what? a mixture of liquids 14 of 27 But they must have what? very different boiling points 15 of 27 The flask will contain what? the mixture of liquids 16 of 27 And it is connected to a ______ _____ containing _____ ___/_____? to a fractionating column containing glass rods/beads 17 of 27 Firstly we should gently? heat up solution 18 of 27 The liquid with the _____ boiling point will begin to _______ first? liquid with the lowest boiling point will begin to evaporate first 19 of 27 However both ______ will enter the what? both vapours will enter the fractionating column 20 of 27 They will then repeatedly do what? cool and condense back into the flask 21 of 27 This allows the ____ with the lower ____ ____ to do what? allows the liquid with the lower BP to make its way up the column 22 of 27 It will then enter the ______ and _____? enter the condenser and cool 23 of 27 We will then collect it in? the beaker 24 of 27 We will the increase the? temperature 25 of 27 And the liquid with the ______ BP will? liquid with the higher BP will enter column and condense 26 of 27 That will also then be? collected 27 of 27
