  1. are negative charged ions that will migrate to a positive electrode callen an anode.
  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.
  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.
  14. Are composed of amino acids bound together by peptide links. react mildly in the body like alkaline.
  15. Call and blood proteins acting a bases are transcribed as
  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?
  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
  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:
  24. Any solution that has a lower H+ concentration or a greater OH- concentration than water is
  25. Acidity or alkalinity is determined by variations of the [H+] above or below
  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/
  28. If a solution has more nanomoles than water it is?
  29. If a solution has less nanomoles than water it is?
  30. Normal physiological range of [H+] in healthy people is.
  31. pH lower than 7
  32. pH higher than 7
  33. A pH change of 0.3 units equal a ____fold change in [H+].
  34. a pH change of 1 unit equals a __fold change in [H+].
  35. Water withing the cells makes up how much of the total body water?
  36. Water outside the cells makes up how much of the water in the total body water/
  37. Extracellular water is found in three places:
    Intravascular, Interstitial, and transcellular
  38. Intravascular water makes up what percentage of body weight?
  39. Interstitial water makes up what percentage of the body weight.
  40. Predominant extracellular electolytes:
    Na, Cl, HCO3
