Solution, Solubility Factors
1. Solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
Suspension is a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye and eventually, they settle out of the mixture.
A colloid is a substance microscopically dispersed throughout another substance.
Unlike colloids, suspensions will eventually settle. The suspended particles are visible under a microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid, in which the suspended particles are smaller and do not settle. Colloids and suspensions are different from solutions, in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
2. a. Gaseous Solution- includes gases or vapors dissolved in one another. Two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas.
b. Liquid Solution- contain a liquid solvent in which gas, liquid, or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution.
c. Solid Solution- is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature.
3. Solubility is the ability of one compound to dissolve in another compound.
4. a. Temperature - Basically, solubility increases with temperature. It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in water, but more soluble in organic solvents.
b. Polarity - "Like dissolves like". Nonpolar solutes do not dissolve in polar solvents and the other way round.
c. Pressure - For
