Question

What is the pH of a 0.1μΜ solution of HCl?

Answer 1

The pH of a solution containing 0.1μΜ H+ is 7

Step-by-step explanation:

The pH of any solution is given by the following mathematical equation -

`pH = -log[H_(+)]\\`----------- Equation (A)

Where,

`H_(+)` = the concentration of hydrogen ion in the solution.

Given

`H_(+) = 0.1 micro meter= 0.1 * 10^(-6) meter= 10^(-7) meter`

Substituting the given value in equation (A) , we get -

`pH = -log[10^(-7)]`

`= -(-7)\\= 7`

Hence, The pH of a solution containing 0.1μΜ solution is 7
