What is the difference between soluble and miscible substances




















In contrast, butanone is a ketone that is significantly soluble in water but it is not miscible with water because the mixing of water and butanone does not form a homogenous mixture.

The term soluble refers to the ability of a compound to dissolve in a solvent. Here, the compound that is being dissolved is named as the solute and it can occur in any one of the three phases of matter it can be a solid, liquid or a gas ; the solvent is usually a liquid, but there can solid and gaseous solvents as well. After the dissolution, the mixture of solute and solvent is named as a solution.

This solution can be either homogenous or heterogeneous because solubility does not describe the mixing in all proportions. The terms miscible and soluble may refer to the mixing of two compounds to form one unit. The key difference between miscible and soluble is that the term miscible refers to the ability to mix a compound with another compound to make a homogeneous mixture, whereas the term soluble refers to the ability of a certain compound to dissolve in a solvent.

When considering the reactants for each process, the reactants may occur in any of the three phases of matter including solid phase, liquid phase and gas phase. Moreover, solubility can result in either a homogeneous or a heterogeneous solution.

The solubility or miscibility of the solute is dependent on the kind of solute and solvent. When a solute and solvent are mixed, they form what is called a solution. A solution is only formed when the solute can be dissolved in the solvent.

Solubility, a more general term than miscibility, refers to the ability of a substance -- specifically, the solute -- to be dissolved in the solvent. The more the substance can be dissolved, the more soluble it is.

Solid solutes generally have a limit on the amount that is soluble, which depends on the kind of solute and solvent. The term miscibility refers to the ability of a liquid solute to dissolve in a liquid solvent. Solubility is a more general term, but it is more often used to mean the ability of a solid solute to dissolve in a liquid solvent.

Miscibility is used when talking about the solubility of -- specifically -- liquid solutes. This Wikipedia article provides a good distinction for miscibility:. Miscibility is the property of substances to mix in all proportions that is, to fully dissolve in each other at any concentration , forming a homogeneous solution.
