types of solutions and their definitions:
Solutions are homogeneous mixtures of two or more substances. The solvent is the substance that dissolves the other substance(s), called the solute(s).
Here are some of the most common types of solutions:
- Saturated solutions: These are solutions in which the maximum amount of solute has been dissolved in the solvent at a given temperature. Any additional solute added will not dissolve and will instead precipitate out of the solution.
- Unsaturated solutions: These are solutions in which there is still room for more solute to be dissolved. Adding more solute will increase the concentration of the solution.
- Supersaturated solutions: These are unstable solutions that contain more solute than a saturated solution at the same temperature. They can be formed by slowly cooling a saturated solution or by adding a seed crystal. Supersaturated solutions will eventually precipitate out the excess solute.
- Buffer solutions: These are solutions that can resist changes in pH. They are made up of a weak acid and its conjugate base, or a weak base and its conjugate acid. Buffer solutions are important in many biological processes, such as maintaining the pH of blood.
- Normal solutions: These are solutions that contain one equivalent weight of solute per liter of solution. Equivalent weight is the weight of one gram of an element or compound that will combine with or displace one gram of hydrogen. Normal solutions are used in analytical chemistry.
- Molar solutions: These are solutions that contain one mole of solute per liter of solution. Molar solutions are also used in analytical chemistry.
- Percentage solutions: These are solutions in which the concentration of the solute is expressed as a percentage of the total volume of the solution. Percentage solutions are often used in cooking and medicine.
