Answer:
The pH of a solution containing 0.1μΜ H+ is 7
Explanation:
The pH of any solution is given by the following mathematical equation -
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given

Substituting the given value in equation (A) , we get -
![pH = -log[10^{-7}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-7%7D%5D)

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