EL pH(potencial de hidrógeno) es importante ya que nos permite ver las
características de las sustancias, y a su vez nos permiten saber si las
macromoléculas biológicas/soluciones biológicas se encuentran en un rango
normal o alteradas; este tiene una formula la cual nos ayuda a saber el
nivel de Ph.

FORMULA: pH=−log10[H+]

El pH es el encargado de saber si una solución es neutra(7) ,
alcalina/base(capta iones de hidrógeno)(mayor a 7-14) o ácida (libera iones
de hidrógeno/protones)(0-menor a 7); un ejemplo de ello es la sangre , esta
tiene un rango de 7,35 a 7,45 ; si esta se encuentra muy alcalina se le llama
alcalosis y si se encuentra muy acida se le llama acidosis.

Para saber la alcalinidad de una sustancia biológica se utilizan indicadores
como el pH colorimétrico (medición más rápida), pH metro(es solo para una
solución en específico) , naranja de metilo (detecta soluciones ácidas),
