Question

What is the concentration of H+ ions at a pH = 11?

Answer 1

pH= -log[H+]
11= -log[H+]
[H+]= 10^-11
1 x 10^-11

Answer 2

Answer:

Concentration of H+ ions = 1.0*10⁻¹¹ M

Explanation:

Given:

pH of a solution = 11

To determine:

The H+ ion concentration of the solution

Explanation:

pH is quantitative parameter which reflects the H+ ion concentration of a solution and hence is indicative of the acidity of the solution.

$pH = -log[H+]\\\\[H+] = 10^{-pH}$

For the given solution:

$[H+] = 10^{-11} = 1.0*10^{-11} M$
