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 -
[tex]pH = -log[H_{+}]\\[/tex]----------- Equation (A)
Where,
[tex]H_{+}[/tex] = the concentration of hydrogen ion in the solution.
Given
[tex]H_{+}[/tex]
= [tex]0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\[/tex]
Substituting the given value in equation (A) , we get -
[tex]pH = -log[10^{-4}][/tex]
[tex]= -(-4)\\= 4[/tex]
Hence, The pH of a solution containing 0.1 mM H+ is 4
