Yes, this method is useful.
first add water to mixture the ammonium chloride and barium chloride dissolve in the water but the iodine does not. filter out the iodine using filtration then use fractional crystallization to separate the ammonium chloride and barium chloride and water
What is a Mixture?a mixture is the process of mixing two or more substancesWhat is a filtration?a filtration is the process of separating a solidand liquid substancesTHAT'S ALL
filtration
we can separate mixture by filtration,distillation,evaporation,precipitation and magnetization
Examples: filtration, decantation, centrifugation.
Four methods are: filtration, distillation, magnetic separation, precipitation.
use sublimation set-up...
separating an insoluble solid from a liquid: decantation, filtration separating a dissolved solid (solute) from a solution: evaporation, crystallization separating the solute and solvent from a solution: simple distillation separating a mixture of two miscible liquids: fractional distillation
that depends on the mixture for eg sand and water can be separated salt and water can't be separated
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
We separate mixtures for many things. It can be used for cleaning (filtering) our water. This is done by FILTRATION;when the substances in a mixture have different particle sizes, they are separated by filtration. The more different the properties are, the easier it is to separate the substances.Read more: SEPARATING MIXTURES http://www.infoplease.com/dk/science/encyclopedia/separating-mixtures.html#ixzz3OjF9dZjT
If you have a solid precipitate /liquid mixture filtration is the better method of recovering the solid as any contaminant in the liquid can potentially be washed out. Evaporating the liquid to remove it would just deposit whatever residues there were onto the precipitate.
