Chapter 3.3-3.4

• Concentration


  quantitative measure of the relative amounts of solute and solvent present in a solution
• Solvent


  solution component present in a concentration that is higher relative to other components
• Dissolved


  describes the process by which solute components are dispersed in a solvent
• Aqueous Solution


  solution for which water is the solvent
• Solute


  solution component present in a concentration less than that of the solvent
• Concentrated


  qualitative term for a solution containing solute at a relatively high concentration
• Molarity (M)


  unit of concentration, defined as the number of moles of solute dissolved in 1 liter of solution
• Dilution


  process of adding solvent to a solution in order to lower the concentration of solutes
• Mass Percentage


  ratio of solute-to-solution mass expressed as a percentage
• Volume Percentage


  ratio of solute-to-solution volume expressed as a percentage
• Mass-Volume Percent


  ratio of solute mass to solution volume, expressed as a percentage
• Parts Per Million (ppm)

  ratio of solute-to-solution mass multiplied by 106
• Parts Per Billion (ppb)

  ratio of solute-to-solution mass multiplied by 109
