Question

Answer the following question in brief: List the factors that affect the formation of the solutions.

Answer 1

1. A solution is a homogeneous mixture of one or more solutes in a solvent.
2. The formation of a solution depends on the solubility of the solute in the solvent.
3. The solubility of a substance depends on the physical and chemical properties of that substance. In addition to this, there are a few conditions which can manipulate it. Temperature, pressure and the type of bond and forces between the particles are few among them. We shall discuss them in detail.
4. Temperature: Sparingly soluble solid or liquid substances can be dissolved completely by increasing the temperature. But in the case of gaseous substance, temperature inversely influences solubility i.e. as the temperature increases gases expand and escapes from their solvent.
5. Forces and Bonds: Like dissolves like. The type of intermolecular forces and bonds vary among each molecule. The chances of solubility between two unlike substances are more challenging than the like substances. For example, water is a polar solvent where a polar solute like ethanol is easily soluble.
6. Pressure: Gaseous substances are much more influenced by solids and liquids by pressure. When the pressure of gas increases, the chance of its solubility is also increased. A soda bottle is an example of where CO₂ is bottled under high pressure.
7. Size of the solute particles: Smaller the size of the solute particles greater the rate of formation of the solution.
