Question

How can the pH of a solution be calculated if the pOH is known?

A) by taking the negative logarithm of pOH
B) by adding the pOH to 14
C) by raising 10 to the power of –pOH
D) by subtracting the pOH from 14

Answer 1

Correct answer choice is :

D) By subtracting the pOH from 14

Explanation:

P is usually done with very small or very large values. To determine the pH of an aqueous liquid you want to know the density of the hydronium ion in moles per liter. The pH is then determined using the expression pH = - log [H3O+].POH is the contrary of the logarithm of the OH- ion concentration. pOH = - log [OH-] pH + pOH = 14, for an aqueous liquid at 25C, despite how many acid or base has been added to the suspension.

Answer 2

If pOH is known, we can calculate the pH of the solution by subtracting the pOH from 14.

What is pH?

pH means potential hydrogen. The pH value tells us about the acidity and basicity of any solution.

The pH of pure water is 7.

The pH less than 7 is considered as acids and those value more than  7 are bases.

To calculate the pH of any compound.

$\bold{pH = -log[H^+]}$

Thus, to calculate the pH of any solution, subtract it from 14.
