Question

Calculate the pH of a C6H5OH phenol solution, whose hydronium ion concentration [H3O +] is 1.8 x 10e-5 M

Answer 1

Answer: The pH of phenol solution is 4.7

Step-by-step 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.

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

Given :
`[H_3O^+]=1.8* 10^(-5)M`

Putting in the values we get

`pH=-\log[1.8* 10^(-5)M]`

`pH=4.7`

Thus pH of phenol solution is 4.7
