Question

The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. A basic solution has a pH of 11.2. An acidic solution has a pH of 2.4. What is the approximate difference in the concentration of hydrogen ions between the two solutions?

Answer 2

Answer:

Step-by-step explanation:

Basic Solution:

pH = -log(H+) = 11.2

=>log(H+) = -11.2

H+ = $10^{-11.2}$

Since basic solution is shown as OH- concentration

OH- = $10^{-2.8}$

Acidic Solution:

pH = -log(H+) = 2.4

=>log(H+) = -2.4

=> H+ = $10^{-2.4}$
