Smoke is an example of solid aerosol in which dispersed phase is solid and dispersion medium is gas.

That gases can dissolve solids has been known since the work of Hannay in 1879-1881. The historical and theoretical aspects of this phenomenon are discussed, and the literature of the subject is summarized and reviewed.

Hint: Smoke is a colloid. A colloid has a dispersed phase and a dispersion medium. Dispersion medium is the medium in which the colloidal particles are present. It can be a solid, liquid or gas.

Although most of us think of solutions as a liquid containing dissolved ions, solids can form solutions as well, in which case we think of one solid as being dissolved in another solid. Solid solution occurs as the result of ions substituting for one another in a crystal structure.

A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm. Common examples of solutions are the sugar in water and salt in water solutions, soda water, etc. In a solution, all the components appear as a single phase.

Solute Examples

A solution can be categorized into several components. On the basis of physical states of solvent and solute can be categorized as solid, liquid and gaseous solutions.

NaCl solution

Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). Hypotonic solutions have more water than a cell. Tapwater and pure water are hypotonic.

Ocean water is a homogenous mixture of salt in water. Ocean water is the type of mixture called a solution, because the salt is dissolved in the water. Water is the solvent, and sodium chloride is the solute. Water dissolves salt when water molecules attract and pull apart the sodium and chloride ions in salt crystals.

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water can become so heavily attracted to a different molecule, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt molecule together and, thus, dissolve it.

Water is The Universal Solvent Being polar gives water its ability to dissolve many things easily. If water wasn’t polar, it could not dissolve other substances and it would not be able to sustain life on earth as we know.

Everything dissolves in water. Stone, iron, pots, pans, plates, sugar, salt, and coffee beans all dissolve in water. Things which dissolve are called solutes and the liquid in which they dissolve is called a solvent.
