Solutions and Their Characteristics
- A solution is a homogeneous mixture of two or more substances.
- A homogeneous mixture has a uniform composition.
- A heterogeneous mixture contains two or more phases.
- Examples of solutions include glucose solution and mixtures of oil and vinegar.
- The solvent is the substance present in the largest amount in a solution.
- The solute is the substance that is dissolved in the solvent.
- An aqueous solution is a solution in which water is the solvent.
- Concentration is the ratio of the amount of solute to the amount of solution or solvent.
- A concentrated solution has a relatively large amount of solute per unit volume of solution.
- A dilute solution has a relatively small amount of solute per unit volume of solution.
Types of Solutions
- Solid dissolved in a liquid solvent: Examples include steel (carbon in iron), syrup (sugar in water), and antifreeze (methanol in water).
- Liquid dissolved in a liquid solvent: Examples include tooth fillings (mercury in silver).
- Gas dissolved in a liquid solvent: Examples include carbonated drinks (CO2 in water) and humidity (water in air).
- Solid dissolved in a solid solvent: Examples include steel in buildings (carbon in iron).
- Gas dissolved in a gas solvent: Examples include natural gas (methane gas dissolved with other gases) and mothballs (molecules that separate and form a solution in air).
