un refresco tiene una concentración de 3.8 x 10-4 de iones H+. determina el valor de PH de ese refresco​
kifflom [539]

Answer:

El pH del refresco es 3.42.

Step-by-step explanation:

Se puede calcular el pH del refresco usando la siguiente fórmula:

pH = -log([H^{+}])

En donde:

[H⁺]: es la cocentración de los iones H⁺ de la solución

Entonces, el pH es:

pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42

El resutlado obtenido nos permite concluir que ese refresco es ácido.

Por lo tanto, el pH del refresco es 3.42.

Espero que te sea de utilidad!
