How could separate the mixture of salt water and saw dust?
Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
Can you separate gravel and sand with a coffee filter?
As salt is soluble in water, mixing salt and sand in water would result in solid sand, and salt water. When poured through a coffee filter, the sand would remain in the filter, while the salt water would flow through. After letting the water evaporate, salt would remain. You will be left with the two separated solids.
How can you separate a mixture of sand salt and sawdust?
To separate a mixture of sand, salt, and sawdust, you can use a combination of physical separation techniques. Firstly, use a sieve to separate the sawdust from the sand. Then, dissolve the salt in water, leaving the sand behind. After the salt has dissolved, use evaporation to recover the salt, leaving the sand separated.
How do you separate salt and flour in water?
To separate salt and flour in water, you can use a process called filtration. Pour the salt and flour mixture through a filter, such as a coffee filter or cheesecloth. The water will pass through the filter, while the salt and flour particles will be left behind.
How can you separate gravel and water?
Sift to separate everything from the gravel. Then use a magnet (If needed) to pull out the iron. Now you are left with sand and salt. Dump this mixture into water. The sand should sink to the bottom. The salt should dissolve. Pour the mixture through filter paper to catch the sand. Boil the water and it will evaporate. Now you are left with salt.
How could separate the mixture of salt water and saw dust?

The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
How do you separate a salt gravel and powder mixture?
1. Put the mixture of gravel and salt in water. 2. Salt is water soluble, gravel not. 3. Filter: the salt is in the solution.
How do you separate sand gravel and water?
To separate sand, gravel, and water, you can use a filtration method. Pour the mixture through a filter such as a sieve or cloth to separate the sand and gravel from the water. The water will pass through while the sand and gravel remain on the filter.
Can you separate gravel and sand with a coffee filter?
As salt is soluble in water, mixing salt and sand in water would result in solid sand, and salt water. When poured through a coffee filter, the sand would remain in the filter, while the salt water would flow through. After letting the water evaporate, salt would remain. You will be left with the two separated solids.
How can you separate sawdust from gravel?
Place the sawdust and gravel mixture in water and stir. Let it sit for a time - the gravel will fall to the bottom and the sawdust will float on the top. Density of gravel is greater than water and density of sawdust (wood) is less than water. The layer of sawdust can be carefully removed by skimming it off water's surface or by pouring gravel and sawdust through a series of mesh screens of varying size (the screens can be used with dry or wet mixture)I would use the difference in density of the two materials. A simple method would be to have a stream of the mixed materials poured from a higher elevation to a lower, with a stream of air blowing across the stream. Being less dense, the sawdust will be blown to one side, the gravel will drop straight down. Of course, you COULD just drop the mixed materials into water- sawdust floats, gravel does not. Sawdust will also burn, where gravel will not. Roasting the gravel at a heat above the combustion point of sawdust will cause it to ignite, burning the sawdust away, leaving gravel. Of course, if you have plenty of time, just turn a few termites loose on the mix- they will eat wood- but not gravel!
How do you separate salt sand and gravel?
Firstly, sift the mixture to separate the gravel from the sand and salt. Now place the sifted mixture into water. The sand will sink to the bottom and the salt will eventually dissolve. Pour this watery mixture through filter paper to catch all of the sand. If you want the salt back in solid form, simply boil the water.
Can salt and sawdust be separated by winnowing?
No, salt and sawdust cannot be separated by winnowing. Winnowing is a process that uses air flow to separate lighter particles like chaff from heavier particles like grains. Since both salt and sawdust are fine particles, they would not separate effectively through winnowing.
How do you separate sand salt and sawdust into pure states?
If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.
How would you separate a mixture of salt gravel and power?
Salt is soluble in water; gravel is separated by filtering the solution or by decantation.Power is not a material.
What method do you use to separate iron filings from sawdust?
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.

Then, dissolve the salt in water, leaving the sand behind. After the salt has dissolved, use evaporation to recover the salt, leaving the sand separated.
How do you separate sawdust from salt and sand without using water?
If the particles are each of different size, these compounds may be separated based on two selective filtrations using appropriately-sized sieves. If this process is not possible, than separation may be accomplished by dissolving the salt in another polar solvent such as liquid ammonia or methanol (about 1 or 2 grams of NaCl will dissolve per 100mL of these solvents). The sand and sawdust could then be separated using their density, as the sawdust would float and the sand would sink. Evaporation the solvent would yield the solid salt.
