Answer:
The pH of a solution containing 0.1 mM H+ is 4
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^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)

Hence, The pH of a solution containing 0.1 mM H+ is 4
