Q. Identify the following separation techniques:
1) it is used to separate water from an insoluble solid .
Answers
Answer:
Filtration or Sedimentation
Explanation:
The most common method of separating a liquid from an insoluble solid is the filtration. Take, for example, the mixture of sand and water. Filtration is used here to remove solid particles from the liquid. Various filtering agents are normally used like filtering paper or other materials.
Answer:
sedimentation, filtration, distillation and condensation.
Explanation:
sedimentation - insoluble particles settle at the bottom of the solvent (water), solvent is later drained out. Applicable for only particles which form sediments.
filtration - solution is passed through a membrane(semi permeable, ex: filter paper) through where only the solvent can pass out leaving the solute particles as filtrate.
applicable for sediment forming substances as well as for suspended solutions.
Distillation and condensation - mixture is distilled(boiled) at a temperature where solvent(water) vapourizes. the vapours are then condensed to water again by passing through a condensation tube. It can be applied for true solutions, suspended solutions as well as sediment forming solutions
