Sagot :
Answer:
1.Gravity separation is the most widely used method for oil emulsion separation. The elements in the well stream such as oil and water have different gravities. The density differences allow water to separate by gravity. With enough time in a non-turbulent state, the differing specific gravities will naturally separate.
2.To separate salt, sawdust and iron, use a magnet to separate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to separate the sawdust. Let the water evaporate, leaving the salt behind.
3.The method of separating components of mixtures by employing magnets to attract magnetic objects is known as magnetic separation. Explanation: The components of the mixture, talc powder, and iron filings can be separated using a magnet.
4.Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
What technique can be used to separate salt?
Separate Salt and Water Using Distillation
You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water
What separation technique is used to separate sand and water?
FILTRATION
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the water passes through the filter paper (it becomes the filtrate
