what are acids and bases?
 | Acid:
a class of compounds whose water solutions tastes sour, turns blue litmus to
red, and react with bases to form salts |
| Base: a class of compounds that taste bitter, feels slippery in water solution, turn red litmus to blue, and reacts with acids to form salts |
how are weak acids and bases compared?
| Strong
acids and bases dissociate completely in aqueous solution; weak one
dissociate only partially |
| An
acid anhydride reacts with water to form an acid. A base anhydrate reacts
with water to form a base |
| Dissociation constants measure the relative strength of weak acids and bases. The smaller the numerical value of this equilibrium constant, the weaker the acid or the base |
what are the biochemical roles of some acids and bases?
| The
pH measures the hydronium ion concentration in a solution |
| Water,
an amphiprotic substance, dissociates to form hydronium ions and hydroxide
ions |
| Amino acids, nucleic acids, and fatty acids are biological molecules that function within the pH range system |
| Buffers maintain pH in living systems |
