  When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue.

  This method is used to separate dissolved solids from a solution.]]> 2018-01-29 12:39:22 UTC https://padlet.com/neo_si_lie_charles/i190kubhaiw0/wish/225582314 An example of a suitable mixture and the description of how the mixture can be separated by the evaporation to dryness. raidon_ng_cho_yeow https://padlet.com/neo_si_lie_charles/i190kubhaiw0/wish/225582368   When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute, also known as the residue, will remain in the evaporation dish.

  An example of this is salt water. If you set a cup of salt water boil over a bunsen burner, the residue will be salt after the water has evaporated.

  Evaporation to dryness cannot be used for solutions like sugar solution as sugar will decompose upon heating.]]> 2018-01-29 12:39:34 UTC https://padlet.com/neo_si_lie_charles/i190kubhaiw0/wish/225582368 The precautions to take note of for evaporation to dryness. https://padlet.com/neo_si_lie_charles/i190kubhaiw0/wish/225949494 1.) Be in proper attire when doing experiment
2.) Be careful when handling hot appliances/apparatus
