Phenol is a weak acid with a Ka = 1.28 x 10-10.  As a pure compound, it is rather corrosive but in the 1800s, it was the first substance used to disinfect surgeons' hands prior to operating.  What is the pH of a 0.060 M aqueous phenol solution?  (Write your answer as a number to two decimal places.)


Expert Answer

Step 1

Phenol (PhOH) will give the below reaction in water.

PhOH ----> PhO- + H+

assuming a concentration of PhOH dissociated in water from above reaction => a moles of PhO- and H+ will pro...
