(A little confused on the BIG words?)
Acid- A substance that has the potential to donate a proton or accept an electron pair.
Acidic- Having a pH less than 7
Base- A substance that can accept a proton, release OH-, or donate an electron pair.
Basic- Having a pH greater than 7.
Buffer- A solution composed of an acid and its conjugate base that serves to moderate the pH of the solution.
Conjugate Base- A molecule that can be described as an acid that has lost one proton.
Conjugate Acid- A molecule that can be described as a base that has gained one proton.
Dissociate- Separate into its ion constituents.
Indicator- A molecule whose conjugate acid or conjugate base has a differnt color.
pH- A measure of the hydrogen ion concentration, it is equal to - log [H+].
Strong Acid- An acid with a pKa less than zero. Strong acids completely dissociate in water.
Strong Base- A base with a pKa less than zero. Strong acids completely dissociate water.
Weak Acid- An acid with a pKa greater than zero. Weak acids do not completely dissociate in water.
Weak Base- A base with a pKa, greater than zero. Weak bases do not completely dissociate in water.
Carbonic- Relating to or consisting of or yeilding carbon.
Homeostasis- metobolic equilibrium actively maintained by several complex biological mechanisms that operate via the autonomic nervous system to offset disrupting changes.
