Chemistry Solutions and Characteristics

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).
