When salt is added into water it becomes a mixture.

Is water a mixture or pure substance. Pure water is called distilled water or deionized water. This is because it has the same material all over and is made of one kind of substance throughout. Water h 2 o is a pure substance a compound made of hydrogen and oxygen.

It contains only h2o molecules. A mixture of oil and water is a mixture not an element. The pure water is one the basic example of a pure substance although this water becomes mixture sooner as the impurities or other substances get mixed in it.

Water is a pure substance. Distilled water is a pure substance. Each of the components of a mixture can be separated from one another.

You can do this by adding water dissolving the salt and then filtering the mixture. Every portion of the mixture is like every other portion.
