In fact, salt water is a solution because salt dissolves in water. A mixture is a mix of substances that can be separated by physical means. Saltwater can be separated by boiling away the water and leaving the salt behind, but because the salt dissolves in water, it is a solution. There are two parts to a solution. The solute and the solvent. The solute is the substance that is dissolved in the solvent. The solute is usually smaller than the solvent. A compound is a substance in which two or more atoms are joined in a chemical reaction. The resalting substance has properties different than those of the starting substances.
