answers shown at the bottom: PH= .18, pOH= 14.18
shouldnt the pOH be 13.82 since, pOH= 14 - PH?
Homework Answers
As we know that,
pH = - log[H+]
Hence, HCl = H+ + Cl-
Since, pH = - log ( 1.5) = - 0.18
We know that, pH + pOH = 14
Hence , the pOH = 14 - (- 0.18) = 14.18
The answer is given correct.
When the molar concentration of an acid is greater than 1M , the pH should be negative.
