The number of atoms or molecules (6.02 x 10 23) whose weight in grams is equal to the atomic mass units of that atom or molecule.
The amount of solute (in moles) per litre of solution
Mixture of chemicals that operate to maintain a constant pH in a solution, mixtures containing a weak acid and the salt of a weak acid
Most of the hydrogen (H+) dissociates (seperates) from chlorine when in solution, lower pH, 1-2
Only a small percentage of the hydrogen (H+) dissociates (seperates) from the acetate when in solution, pH roughly 4-6
Salt of Acid
Anion (an ion w/negative charge) formed after dissociation (seperation)
("unchanging") describes the body's ability to maintain relatively stable internal conditions even though the outside world changes continuously. The body must keep a balanced or dynamic state of equilibrium in which internal conditions might vary, but within narrow limits. Virtually every organ system plays a role in maintaining the constancy of the internal eviroment. Ex: nutrient levels in the blood stream heart activity, and waste removal.
Ionic compounds (compounds that form as a result of attraction between ions) seperate in solution.
When atoms gain or lose electrons, they form ions.
Measurement scale that indicates the relative concentration of H+, the degree to which a solution is acidic or basic.
Atomic Mass Unit, A unit of measure used to describe the mass of atoms; equal to 1.67 x 10-24(negative 24) grams, appoximately the mass of one proton.
6.023 x 10 23power, 1 mole, a mole is equal to the atomic weight in grams of any atom(element). Ex: 1 mole Cl=6.023 x 10 23power Chlorine atoms=35.5 grams of Chlorine atoms.
Substances that conduct an electrical current in solution, all ions are electrolyts, electrolytes include salts, acids, and bases.
Only a small portion of their Hydroxyls dissociate when in a solution. pH=8-10
Nearly all of the hydroxyls dissociates when in a solution. ph=12, 13, and 14
