By evaporating the water of the solution and condensing it.
No. Pure water is a compound, which is a pure substance. A saltwater solution is a mixture of water and salt, and is not a pure substance.
No, a salt solution is not a pure substance. It is a mixture of salt (solute) dissolved in water (solvent). A pure substance contains only one type of element or compound with a fixed chemical composition.
A saline solution is a homogeneous mixture because its appearance and composition are uniform throughout the solution. A substance is salt. A saline solution is a combination of the two substances water and salt. However, in the salt-water solution, the salt is completely dissolved in the water.
Salt water is a solution, which is a homogeneous mixture of two or more substances. In this case, salt (solute) is dissolved in water (solvent) to form salt water.
i think by distillation..we can get pure water and salt
Pure NaCl, common salt, is a chemical compound and "one pure substance". (Table salt often has small amount of an iodide salt added for health reasons, and some anti-caking agent to make it flow better)
Cooling a salt solution will crystalize the salt presumably by lowering the solubility, allowing the solution to be filtered and pure water obtained. Drinking salt water will lead to dehydration.
Pure water has a higher freezing point than 20% salt water.
Pure saline water is only a solution of sodium chloride in water.
No, salt water is generally denser than pure water due to the dissolved salt particles increasing the overall mass of the solution. This increased density causes objects to float higher in salt water compared to pure water.
Firstly, pure salt is white and it becomes colourless when dissolved in water. Secondly, solid salt is a non-conductor of electricity, whereas the solution is an electrolyte and conducts well.
pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.
