Basically, water is known as a solvent and salt is known as a non-volatile solute. When you add something like salt to a solvent like water, it makes water become an impure solvent and raises its boiling point above that of pure solvents. Though salt raises the boiling point of water, it doesn’t do it very much.
Effects of soluble salts on coating life general effects soluble salts can affect the ability of coatings to protect steel in several ways. Salts that remain on the substrate can result in blistering of the coating. This phenomenon, known as os-motic blistering, can produce pressures of several thousand psi, which is enough to cause the coating.

Salinity is a measure of the total amount of soluble salts in soil. As soluble salt levels increase, it becomes more difficult for plants to extract water from soil.
Salts also have the effect of increasing the rate of absorption of moisture from the atmosphere by lowering the threshold relative humidity for condensation.
The solubility of a given salt in a given solvent depends on temperature (definitely) and pressure (maybe). In general, solubility of an ionic compound depends on the ability of the solvent molecules to separate the charged species making up that.

Excessive soluble salts in the soil root zone can also come from soil amendments with high salt concentrations like manure/composted manure, de-icing materials, sea-spray or flooding from seawater. High soluble salt levels in the soil can cause plant drought stress. Water in the soil is drawn away from tender plant roots to the nearby high.
The solubility of a given solute in a given solvent typically depends on temperature. Many salts show a large increase in solubility with temperature. Some solutes exhibit solubility that is fairly independent of temperature. A few, such as cerium(iii) sulfate, become less soluble in water as temperature increases.

The common ion effect is observed whenever an ion in solution is common to two different salts which serve as its sources.

Additives or salts that increase solubility in given solvent are said to “salt in” the solute and those salts that decrease solubility “salt out” the solute. Several salts with large anions or cations that are themselves very soluble in water result in “salting in” of non electrolytes called “hydrotropic salts”; a phenomenon.
