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.
\(pH=-\log (1.0\times 10^{-11})\)
\(pH=-\log (1.0)-\log (10^{-11})\)
\(pH=-0-(-11)\)
\(pH=11\)
Therefore, the pH of the solution is, 11
