is 14.0. pOH
is 5 - 0.568 or about -4.33, and the pH must be 14.00 - 4.33 or 9.7
, to the justified number of significant digits.
Acidic
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What is the concentration of the hydroxide ion given that the concentration of the hydronium ion is 1.5x10-5M?Read more: What_is_the_concentration_of_the_hydroxide_ion_given_that_the_concentration_of_the_hydronium_ion_is_1.5x10-5M
4.0x 10^ -11
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
Acidic
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
Yes, in fact an acidic solution is, by definition, one where the hydronium ion concentration is higher than the hydroxide ion concentration.
basic
In this case the pH increase over 7.
.48 = [OH-]
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.

2.5 x 10-2
The hydroxide ion concentration equals the hydronium ion concentration at a (neutral) pH of 7
