Question

Calculate the ph pf 1* 10 ^-4 molar solution of hno3

Answer 1

Answer:

pH is a scale by which the nature of a solution is measured.

If the pH of the solution is less than 7, it will be an acidic solution.

If the pH of a solution is greater than 7, it will be a basic solution.

Solution will be neutral if the pH is equal to 7.

Given: 1.0 x 10^{-4} molar solution

HNO_{3} is a strong acid

So, [H^{+}] = 1.0 x 10^{-4}

We know that  pH = - log [H^{+} ]

 pH = - log [ 1 x 10^{-4}[/tex]

        = - [-4]

 pH = 4.
