Buffering of Solutions

Acids= H+-donating substance

Bases= H+-accepting substance

• Loss of a H+ is called ionization and the ìstrengthî of an acid or base is determined by the extent to which it ionizes in water

HCl _ H+ + Cl-

• Thus, it is the ionization of H+ that is the biologically significant factor and not the molecule itself

• Lactic Acid-H+ _ Lactate- + H+
