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)
Yes salt is a compound of Sodium and Chlorine
Yes it is a pure substance. Because when it mix with water you can't see the salt anymore because it dissolve and leave the water in the same color.
A solution means the mixture of at least two substances solute and solvent so a solution can not be a pure substance.
Saline water is a mixture of sodium chloride and water.
Salt water is a solution.
A salt solution is a homogeneous (uniform) mixture of salt and water, and is not a pure substance.
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.
Neither "substance" nor "mixture" is an apt designation for salt water. Salt water is best described as a "solution of salt in water". It would be a good idea for you to review the difference between "mixture" and "solution".
no, solutions are not pure substances because all though they may look that way to the naked eye, the definition of a solution is a mixture where one substance has completely dissolved into the other. such as salt water. you can see only the water but you know the salt is there because when it dries out, the salt is left over.
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.
A salt solution is a homogeneous (uniform) mixture of salt and water, and is not a pure substance.
Salt water is a solution.
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.
no , its a mixture. salt is a pure substance, as is water, but togher they are a mixture.....
Seawater is a mixture. It is a combination of salt and water that is a homogeneous mixture. An example of a pure substance is either pure salt or pure sugar.
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).
