Question

Does solubility differ from molar solubility?

Answer 1

Solubility refers to a solute's ability to dissolve in a solvent.
The solubility of a particular solute in a given solvent is influenced by a number of factors. Temperature is generally the most important factor, however pressure can have a major impact on gases. Remember the phrase "like dissolves like" when predicting whether a chemical will be soluble in a particular solvent. Salt and other highly polar ionic chemicals dissolve quickly in polar water, but not in non-polar solutions like benzene or chloroform.

Complete answer:
The ability of a solid, liquid, or gaseous chemical substance called a solute to dissolve in a solid, liquid, or gaseous solvent is known as solubility. The physical and chemical characteristics of the solute and solvent, as well as the temperature, pressure, and presence of other chemicals (including variations in pH) in the solution, all influence the solubility of a material. The saturation concentration of a material in a given solvent is the point at which adding more solute does not raise the concentration of the solution and begins to precipitate the excess quantity of solute. The inability to dissolve in a solid, liquid, or gaseous solvent is known as insolubility.
Because a solution can form as a result of a chemical process, solubility should not be mistaken with the capacity to dissolve a material. Zinc, for example, dissolves (with effervescence) in hydrochloric acid as a result of a displacement process that releases hydrogen gas. In the acid, the zinc ions are soluble. A substance's solubility is distinct from its rate of solution, which refers to how quickly it dissolves. Although there are numerous variables to consider, the smaller a particle is, the faster it dissolves.
The solubility product (${{K}_{sp}}$) of a substance is the ratio of equilibrium concentrations. The number of moles of the solute that may be dissolved per litre of solution before the solution becomes saturated, which is directly connected to the solubility product. Any extra solute precipitates out of a solution once it is saturated. Molarity (M) (mol/L) are the units.

Note:
The degree of solubility varies greatly across substances, ranging from endlessly soluble (totally miscible) ethanol in water to moderately soluble silver chloride in water. Poorly soluble chemicals are sometimes referred to as "insoluble." The equilibrium solubility can be surpassed under certain conditions, resulting in a supersaturated solution. Particle size has little bearing on solubility; given enough time, even huge particles will dissolve.
