Acid-Base Balance Flashcards
acid–base balance refers to the
precise regulation of free (that is, unbound) hydrogen ion (H+) concentration in the body fluids.
Acids are a special group of
hydrogen-containing substances that dissociate, or separate, when in solution to liberate free H+ and anions
A strong acid has a greater tendency to
dissociate in solution than a weak acid does
Hydrochloric acid (HCl) is an example of a strong acid; every HCl molecule dissociates into free H+ and chloride (Cl2) when dissolved in H2O
With a weaker acid such as carbonic acid (H2CO3), only a
portion of the molecules dissociates in solution into H+ and bicarbonate anions (HCO3-).
The extent of dissociation for a given acid is always
constant
