Answer: The pH of phenol solution is 4.7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration.
[tex]pH=-\log [H_3O^+][/tex]
Given : [tex][H_3O^+]=1.8\times 10^{-5}M[/tex]
Putting in the values we get
[tex]pH=-\log[1.8\times 10^{-5}M][/tex]
[tex]pH=4.7[/tex]
Thus pH of phenol solution is 4.7
