Distillation 6 marker:
Remember this is used for the oxidation of a primary alcohol t
an aldehyde.
• place the impure distillate in a separating funnel
• add sodium carbonate solution
• stopper and shake
• release pressure
• separate the layers
• add anhydrous calcium chloride
• until the liquid is clear
I
filter off solid
Titration 6 marker:
Remember methyl orange = strong acids
Phenolphalein = strong bases
• Add … to methanol until no more dissolves
• Add … to water until no more dissolves
• Filter the mixtures
• Titrate equal volumes of each … solution with a standard
solution of sodium hydroxide
• Phenolpthalein indicator
• Colourless to pink
• Ibuprofen is more soluble in the solvent which requires the
greater
volume of sodium hydroxide solution.
