Separating a mixture of sugar and Sulphur can be done using water. Sugar is soluble in water while Sulphur is not. Add water to the mixture, stir, and then filter the solution. The Sulphur remains on the filter paper, and the sugar dissolves in the water. Collect the filtrate and evaporate the water to retrieve the sugar.

FAQs & Answers

  1. Why does sugar dissolve in water but sulphur does not? Sugar is a polar substance, making it soluble in polar solvents like water, while sulphur is non-polar and insoluble in water.
  2. What is the best method to separate sugar from a mixture with sulphur? The best method involves adding water to dissolve sugar, filtering out insoluble sulphur, and then evaporating the water to recover the sugar.
  3. Can other solvents be used to separate sugar and sulphur? Water is the preferred solvent because sugar is soluble in it while sulphur is not; other solvents may not provide effective separation.
