Answer : The correct option is, (C) 11

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

Mathematically, it is represented as :

$pH=-\log [H^+]$

or,

$pH=-\log [H_3O^+]$

Now we have to calculate the pH of the solution.

$pH=-\log [H_3O^+]$

Now put the value of hydronium ion concentration in this expression, we get the value of pH of the solution.

$pH=-\log (1.0* 10^(-11))$

$pH=-\log (1.0)-\log (10^(-11))$

pH=-0-(-11)

pH=11

Therefore, the pH of the solution is, 11
