Solutions are present on this planet in phases of solids, liquids, and gases along with different combinations. Even in these phases, the solute and solvent mix completely and evenly which classifies them as perfect solutions. Mentioned below are the different types of phase combinations:Solid: Solutions that consist of solid solute which is mixed with solid solvent can be termed as a solid solution. For ex: brass is composed of zinc and copper and steel is a product of carbon and iron. Gases: solutions that consist of a gas solute and a solid solvent can be termed as gases solution. For ex: hydrogen which is a solute is dissolved in palladium which is a solvent. Liquids: solutions that consist of liquid solute and liquid solvent can be termed as liquid solutions. For ex: solution hexane and heptane are pure liquids.
