how will you distinguish a solution and a compound ?
In a compound, two or more elements are chemically bound together. On the other hand, in a solution, the substances do not chemically bind together they are held together by weak interactions between them.
In a compound, elements are present in defined ratio, while on the other hand in a solution, the components are not necessarily present in definite amounts.
The components in a solution can be separated by physical methods, but in a compound, this cannot be done by simple physical techniques.
