    Solutions and Their Characteristics

    • A solution is a homogeneous mixture of two or more substances
    • A homogeneous mixture has a uniform composition
    • A homogeneous mixture contains only one phase
    • A heterogeneous mixture contains two or more phases
    • Examples of homogeneous mixtures include glucose solution and air
    • Examples of heterogeneous mixtures include oil and vinegar
    • The solvent is the substance present in the largest amount
    • The solute is the substance that is dissolved in the solvent
    • An aqueous solution is a solution where water is the solvent

    Components of a Solution

    • Concentration is the ratio of solute to solution or solvent
    • A concentrated solution has a large quantity of solute in a given volume of solution
    • A dilute solution has a small quantity of solute in a given volume of solution

    Types of Solutions

    • Solids dissolved in liquids
      • Steel (carbon in iron)
      • Tooth fillings (mercury in silver)
    • Liquids dissolved in liquids
      • Syrup (sugar in water)
      • Antifreeze (methanol in water)
    • Gases dissolved in liquids
      • Carbonated drinks (CO2 in water)
    • Solids dissolved in solids
      • Alloys (e.g., steel)
    • Gases dissolved in gases
      • Air (oxygen and other gases)
    • Liquids dissolved in gases
      • Humidity (water in air)
    • Gases dissolved in solids
      • Natural gas (methane dissolved in other gases)
