In mathematics, the base-b cologarithm, sometimes shortened to colog, of a number is the base-b logarithm of the reciprocal of the number. It is equal to the negative base-b logarithm of the number. In chemistry, a decimal cologarithm is indicated by the letter p. This usage originated with the quantity pH, defined as –log10 [H3O+]. Based on pH, the quantity pKa was later defined as –log10 Ka.

  • Se denomina cologaritmo en base b de un número x, al logaritmo en base b de su inverso 1/x. Aplicando las propiedades de los logaritmos, se cumple entonces que: Se puede afirmar que si A y B son inversos, es cierto que: , por lo tanto .
  • En mathématiques, le cologarithme d'un nombre est défini comme le logarithme de l'inverse de ce nombre, ou encore comme l'opposé du logarithme de ce nombre.Cette notion est utilisée principalement en chimie par l'opérateur pX qui associe à X son cologarithme décimal. Par exemple, le pH en solution aqueuse diluée est défini par : où [H3O+] est la concentration en ions hydronium. L'entropie de Shannon utilise un cologarithme en base 2 (bits) ou en base naturelle (nats), mais ce mot n'est pas utilisé dans ce domaine. * Portail de l’analyse Portail de l’analyse
  • Il cologaritmo è il logaritmo dell'inverso del numero considerato. Il simbolo utilizzato per rappresentarlo è colog.
