  1. are negative charged ions that will migrate to a positive electrode callen an anode.
    Anions(-)
  2. What are the two ways to quantify the amount of solute in a solution:
    By actual weight or by chemical combining power.
  3. Are the amounts of substances that have equal chemical combining power.
    Equivalent weights
  4. What are the two values or equivalent weights that are used to cal chemical power?
    Gram and milligram equivalent.
  5. gEq and mEq
    gram equivalent and milligram equivalent.
  6. formula for gEq
    = atomic weight/ valence
  7. How do you calc. gEq for an acid.
    divide the atomic weight by the nuber of hydrogen atoms that are replaceable in its formula.
  8. The relationship of the solute to the solvent is expressed as a proportion. These are used often in describing concentrations os drugs or pharmaceuticals.
    Ratio solution
  9. this is used for solids dissolved in liquids.Not a true percent solution
    weight per volume W/V
  10. this solution is the weight of solute per weight of solution. It is a true percent solution
    percent solution
  11. are compounds that increase the hydrogen ion concentraion when placed in an aqueous solution.
    Acid
  12. An acid is any compound that is a proton donor. This includes substances other than traditional acids such as the ammonium ion.
    Bronsted-Lowry's deinition
  13. is a compound that gives up a hydroxyl ion when placed into an aqueous solution.
    Base
  14. Are composed of amino acids bound together by peptide links. react mildly in the body like alkaline.
    Proteins
  15. Call and blood proteins acting a bases are transcribed as
    port-
  16. effect is produced by imidazole group of the amino acid histidine ( cyclic crystalline base)
    Hemoglobin Buffering Group
  17. The O2 carrying component of hemoblobin is attached to a histidine residue. What is it called?
    Heme
  18. The ability of hemoglobin to accept H+ ions depends on the?
    Oxygenation state of the molecule.
  19. Which is a stronger base: Deoxigenated (reduced) or oxygenated hemoglobin
    deoxigenated
  20. These also act as buffers, but with less buffering power than hemoglobin, which contains more histidine.
    Plasma Proteins
  21. Pure water can be used as a reference point for determining:
    Acidity or alkalinity
  22. The concentration of both H+ and OH- is pure water is:
    10^7 mmol/L
  23. Any solution that has a greater H+ concentration or lower OH- concentration than water acts as:
    Acid
  24. Any solution that has a lower H+ concentration or a greater OH- concentration than water is
    Alkaline
  25. Acidity or alkalinity is determined by variations of the [H+] above or below
    1x10^-7
  26. what are the two ways to record pH of a substance:
    [H+] in nanomoles per liter or logarithmic pH scale
  27. How many nanomoles per liter of water is there when its neutral/
    100
  28. If a solution has more nanomoles than water it is?
    acidic
  29. If a solution has less nanomoles than water it is?
    alkaline
  30. Normal physiological range of [H+] in healthy people is.
    30-50nnmol/L
  31. pH lower than 7
    acidic
  32. pH higher than 7
    Alkaline
  33. A pH change of 0.3 units equal a ____fold change in [H+].
    twofold
  34. a pH change of 1 unit equals a __fold change in [H+].
    tenfold
  35. Water withing the cells makes up how much of the total body water?
    2/3
  36. Water outside the cells makes up how much of the water in the total body water/
    1/3
  37. Extracellular water is found in three places:
    Intravascular, Interstitial, and transcellular
  38. Intravascular water makes up what percentage of body weight?
    5%
  39. Interstitial water makes up what percentage of the body weight.
    15%
  40. Predominant extracellular electolytes:
