The ph of a solution containing 0.1 mm h+ is ( 1mm = 10-3m)

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 -

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