A solution is made by mixing two or more different types of substances. Solutions have different types of concentration Units. These units include Molality, Mole fractions, and Molarity. Solutions have types that differ from the mixing of types of Matter. Raoult&#8217;s law has much interference in Solutions. The percentage or amount of solute added in solution is termed as Solubility. Solutions have their different Colligative Properties. Hydration and Hydrolysis tell us about the interactions of different ions, salts, and other particles of Solution. So, this is the brief introduction of this chapter.
