Show answers Print Version (with answers) Show The various methods of separating mixtures find a wide range of applications in industry. This particular task involves analysing and using solubility data to see how salts can be separated by crystallisation. Task 1: Producing a graph to represent solubility data
Model 1
SummaryThe solubility of a salt can be accurately described using a graph. In addition to plotting it accurately, and using the best line or curve, it is important to make sure that the correct units are clearly shown on all data tables and graph axes. Task 2: Interpreting and using the solubility graph
SummaryFrom a basic graph of data you can read of the solubility at any temperature within the data limits. You can do simple proportion calculations for any mass of salt or water to calculate how much is dissolved based on g salt / 100 g of water. Task 3: Using the solubility graph to decide on crystallisation conditions
SummaryOnce you have a database of solubility (or other data) you can make accurate predictions without having to do lots of experiments. Let the computer take the strain! Teacher Summary
