Taya2010 [7]

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 -

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

Where,

H_{+} = the concentration of hydrogen ion in the solution.

Given

H_{+}

= 0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\

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

pH = -log[10^{-4}]

= -(-4)\\= 4

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