15 de jul. de 2021 · El pH es una medida que sirve para establecer el nivel de acidez o alcalinidad de una disolución. La “p” es por “potencial”, por eso el pH se llama: potencial de hidrógeno. Se expresa como el logaritmo negativo de base 10 de la concentración de iones hidrógeno. La siguiente ecuación representa esta definición:
The neutral value of the pH depends on the temperature and is lower than 7 if the temperature increases above 25 °C. The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases.
El potencial de hidrógeno ( pH) es un Índice utilizado ampliamente en química, que expresa el grado de acidez o alcalinidad de una disolución acuosa 1 . El pH está relacionado con la concentración iones de hidrógeno presentes en determinadas disoluciones.
pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion —which ordinarily ranges between about 1 and 10 −14 gram-equivalents per litre—into numbers between 0 and 14.
