Answer: Option (a) is the correct answer.
Explanation:
pH is the negative logarithm of concentration of hydrogen ion.
That is, pH = -log [tex][H^+][/tex]
Hence, pH of solution with [tex][H^+] = 1 \times 10^{-11}[/tex] is calculated as follows.
pH = -log [tex][H^+][/tex]
= -log [tex](1 \times 10^-{11})[/tex]
= 11
Therefore, pH of solution with [tex][H^+] = 1 \times 10^{-11}[/tex] is 11.
