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.
