An ideal solution is a hypothetical solution in which the solute and solvent are perfectly mixed at the molecular level. This means that the solute and solvent are indistinguishable from each other, and there is no physical separation between them. Ideal solutions obey the laws of thermodynamics, which state that the temperature, pressure, and volume of an ideal solution are independent of the amount of solute or solvent present.
In contrast, a real solution is an actual solution in which the solute and solvent are not perfectly mixed at the molecular level. This means that the solute and solvent can be distinguished from each other, and there is some physical separation between them. Real solutions do not obey the laws of thermodynamics as closely as ideal solutions, and their properties are therefore different from those of ideal solutions.
Real solutions are commonly encountered in chemistry, especially when studying solute-solvent interactions, phase changes, and chemical reactions. The properties of real solutions can be very different from those of ideal solutions, depending on the strengths of the solute and solvent bonds.
Here are some examples of real solutions:
A solution of salt in water
A solution of sugar in water
A solution of oil in water
These are just a few examples, and there are many other real solutions in the world. Real solutions can be classified based on the strength of the solute-solvent bonds, such as:
Strong ionic solutions: The solute and solvent have strong ionic bonds, such as sodium chloride (NaCl).
Weak ionic solutions: The solute and solvent have weak ionic bonds, such as potassium hydroxide (KOH).
Covalent solutions: The solute and solvent have covalent bonds, such as carbon disulfide (CS2).
Metallic solutions: The solute and solvent are metals, such as gold (Au) and silver (Ag)
