Real solution definition

In chemistry, a real solution is a homogeneous mixture of at least two chemical substances. A “real” solution differs from a colloidal solution (colloid). According to the concentration of the solute, a distinction is made between hypotonic solution, saturated solution, unsaturated solution.

Properties of a real solution

• the real solution is clear
• the substance is so finely distributed in the solvent that the particles are not visible
• real solutions penetrate porous filter material without leaving residues

Dissolving is a physical process. A solution consists of at least one dissolved solid, liquid or gaseous substance (solvate) and of the majority of the solution, usually liquid or also solid solvent (solvent), which in turn can be a solution.

Solutions are not externally recognizable as such because they only form a homogeneous phase: the solutes are molecules, atoms or ions that are homogeneous and statistically distributed in the solvent. You are e.g. with special filtration methods such as nanofiltration and reverse osmosis.

A homogeneous mixture of different substances in which the fragmentation extends to the level of the molecules, atoms or ions. In an aqueous sugar solution, the sugar molecules between the water molecules so evenly distributed that each volume part of the solution contains the same number of sugar or water molecules. So the solution is composed in the same way everywhere (homogeneous). The term solution is not limited to liquids as solvents and solids as solutes. The ratio of dissolved to solvent is given by the concentration of the solution. As a rule, a solution means those that are formed by dissolving and evenly distributing a gaseous, liquid or solid substance in a liquid solvent.
