  19. Acid
    Soluble compound that has Hydrogen as the positive ion
  20. Aqueous
    homogeneous mixture of a substance and water
  21. Base
    compound that has hydroxide as an ion (OH)
  22. Dissociate
    a solid ionic compound seperating into its ions
  23. Dissolve
    Literally, to loosen. Used to describe the process in which one substance mixes with another. When a solid dissolves in a liquid, the particles that form the solid are released into solution.
  24. electrolytes
    a substance which forms ions in an aqueous solution
  25. Endothermic
    process which absorbs thermal (heat) energy.
  26. Exothermic
    term used to describe a reaction or process that releases energy in the form of heat.
  27. insoluble
    not soluble in water (i.e. oil)
  28. Product
    A substance that is formed as the result of a chemical reaction.
  29. Reactant
    the initial substances in a chemical reaction.
  30. soluble
    dissolves in solution
  31. solute
    The substance that is dissolved in a solution. For solutions of fluids, the solvent is present in greater amount than the solute.
  32. solvent
    The component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved.
  33. titration
    labratory procedure used to determine the amount of a substance in a solution
  34. electron configuration
    a representation that shows the occupation of orbitals by electrons for a particular element.
  35. excitation
    energy is absorbed
  36. Exclusion Theory
    Up to two electrons can occupy one orbital at a time.
  37. frequency
    the number of wave cycles or crests that pass through a stationary point in one second
  38. infrared
    the fraction of the elecromagnetic spectrum between between visible light and microwaves. invisable to the human eye
  39. light
    • has no mass
