Solubility Flashcards
What are the many ways in which you can separate mixtures?
Filtering Chromatography Distillation (Evaporation + Condensation) Evaporation (boiling) Sieve/Collared Magnets Decanting/Separating Funnel
How do you use the separating mixture of chromatography?
Take chromatography paper and draw a line with pencil 2cm from the bottom. (Put crosses at equal intervals on the line if checking for more than one ink. If checking for one ink then out a cross in the middle of the line.)
On each cross, put a dot of the ink you are testing for.
Fill a beaker with some water.
Place the paper in the water and watch the ink separate into different colours.
What equipment is needed in distillation?
A Bunsen burner, Round - bottomed flask, Thermometer, Condenser, Product flask.
How do you use the separating mixture of distillation?
Distillation involves evaporation and condensation.
If you had salt and water, then you would pour it into the round bottomed flask and place a Bunsen burner underneath it. This will evaporate the water, but the evaporated water will not escape as the thermometer is blocking the gateway. The gas will travel down the condenser and turn into a liquid again and fall into the product flask, leaving you with the salt in the round bottomed flask and the water in the product flask. The two are separated.
How do you use the filtering separator?
If you had sand in water, then you would get a funnel, put filter paper in it and pour the sand and water down it. The sand will go through into the beaker you should have under the funnel and the sand will stay in the paper.
How would you separate a substance by boiling it?
If you had salt and water, then you could put it in a beaker and place it on a properly set up Bunsen burner. The water will evaporate leaving you with salt crystals.
