A mixture of sulphur powder and water can be separated by filtration.
What is the filtration?
Filtration is a method for separating an insoluble solid from a liquid. Filtration may be done cold or hot, using gravity or applying vacuum, using a Buchner or Hirsch funnel or a simple glass funnel. The exact method used depends on the purpose of the filtration, whether it is for the isolation of a solid from a mixture or removal of impurities from a mixture. Sulphur is insoluble in water, we will use a filtration technique to separate sulphur from water by passing the mixture through filter paper placed inside a funnel and collecting the water (filtrate) in some beaker. Sulphur will remain on the filter paper.
