For the given mixture, explain a method to separate them. Sugar and water

A saturated sugar solution is a homogeneous mixture whose particles are evenly distributed throughout the solution. The method for separating sugar from the solution is evaporation. The solution is subjected to the heat to evaporate the excess of water. The solid sugar is thus obtained.

For the given mixture, explain a method to separate them. Sand and water

The mixture of sand and water is a heterogeneous mixture. Though sand is insoluble in water it gets settle at the bottom when the mixture is remained undisturbed for some times. Sand can be removed from water by the method of filtration. Filtration is used to remove insoluble impurities from the solution.
