Detailed explanation-1: -Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture.

Detailed explanation-2: -The solution of salt in water is considered a mixture because the salt solution is made up of salt and water. The constituents of the salt solution might be variable. It does not have a fixed ratio and its properties depend upon the nature of its components.

Detailed explanation-3: -Common salt is a compound made up of Sodium and chlorine atom. These elements are combined chemically in a fixed ratio to form Common salt. We can not separate these components easily by physical means. So, Common salt is a compound, not a mixture.

Detailed explanation-4: -Salt water is a solution because it has these two characteristics: it has the same concentration of each of its parts throughout the solution, and it can be separated by some physical process. stands for the element hydrogen, and the O stands for the element oxygen.
