sugar solution is a mixture because
a it is made up of two substances
b both sugar and water are compounds
c sugar can be seperated from water by crystallisation
d a little heat is given out when sugar dissolves
A sugar solution is a mixture because sugar can be separated from water by crystallisation (c).
Mixtures are combinations of two or more pure substances that maintain their compositions. No new substances are made in a mixture. In other words, no chemical reaction occurs. The ratio of the substances that make up a mixture cab vary. For example, salads are mixtures. However, the salads that two people make from a salad bar can look (and taste) drastically different.
All solutions are mixtures. Crystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid. The solution is warmed in an open container. This allows the solvent to evaporate and leaves a saturated solution. As the saturated solution begins to cool, the solid comes out of the solution and crystals begin to grow. The crystals can then be collected and allowed to dry.
