cologarithm การใช้

• In chemistry, a decimal cologarithm is indicated by the letter p.
• Where " dn " is an infinitesimal amount of added base and " d " ( p [ H + ] ) is the resulting infinitesimal change in the cologarithm of the hydrogen ion concentration.
• We can also define p " K " w =  " log 10 " K " w = 14 at 25 癈 . This is analogous to the notations pH and p " K " a for an acid dissociation constant, where the symbol p denotes a cologarithm.
