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)
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.
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.
Salt water is a homogeneous mixture called a solution containing salt and water. Salt is the solute and water is the solvent. It is a mixture because the salt and water are not chemically combined and are not present in definite proportions.
In a salt solution, the salt is the solute and the substance in which the salt dissolves is the solvent. For example, in a saltwater solution, salt (sodium chloride) is the solute and water is the solvent.

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.
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.
no , its a mixture. salt is a pure substance, as is water, but togher they are a mixture.....
ocean water is not a pure substance because it has to particles salt and water so there for it does not have a1 particle so it is a pure substance
no Its a solution. If you mix salt in water, the salt dissolves. It is then a solution. That is not a mixture. It may well be a pure substance. If it is pure salt water it is pure. But if you add some soap it is then pure soapy salt water. What does pure mean? Pure is not a scientific term, so its meaning is debatable. Pure orange juice for instance, has no real meaning as orange juice contains many different things, so how is it pure? In fact if by the previous persons definition of pure, [wood is not but glass is] is incorrect as glass is a compound of several things as is wood. Pure water is a compound of hydrogen and oxygen. So is that pure ,or not?
By evaporating the water of the solution and condensing it.
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
It is a mixture of a salt compound (e.g. NaCl, NaCO2, LiCl, LiCO3, etc.) and water (or another fluid).
In a salt solution, water is the solvent because it is the substance that dissolves the salt. The salt is considered the solute because it is the substance that is being dissolved in the water to form the solution.
Table salt is a pure substance. A pure substance is a substance has one type of molecule and one type of atom. Other pure substance are copper and liquid water.
