A glass cup of orange juice is found to have pOH of 11.40. Calculate the concentration of the hydrogen ions in the juice.​

Respuesta :

Ajiduah1

Answer: The concentration of hydrogen ion is 2.5 x 10∧-3.

Explanation:

It is well known that; pH + pOH = 14

∴ pH + 11.40 = 14

  pH = 14 -11.40 = 2.60

Remember that,

pH = - Log [ H+ ]

2.60 = - log [H+]

To get the  hydrogen ion concentration, we take the anti-log of 2.60.

[H+] = Antilog 2.60 = 2.5 x 10∧-3.
