Answer:
the pH of the solution = 9
Explanation:
pH -
The value of pH is used to determine the acidic strength of the solution , depending on the connection of the H⁺ ions in the solution.
pH is given as negative log of the H⁺ concentration.
Since,
pH = - log [ H⁺ ]
Similarly ,
pOH = - log [ OH⁻ ]
The relation between pH and pOH is -
pH + pOH = 14
From the question,
[OH⁻] = 1 * 10⁻⁵
pOH = - log [ OH⁻ ]
pOH = - log [ 1 * 10⁻⁵ ]
pOH = 5
Therefore,
pH + pOH = 14
pH + 5 = 14
pH = 9
Hence, the pH of the solution = 9
