Answer
pOH = 4.1
Explanation
<em>Given:</em>
pH = 9.9
<em>Required</em>: The concentration of OH-
Solution
pH + pOH = 14
9.9 + pOH = 14
pOH = 14-9.9
pOH = 4.1
The answer is A. the solar ultraviolet ray breaks the molecule apart
14 Molar is its molarity.
B) Equal to the number of protons
Seems to be 3.6 since it’s closer by 1, As for 4.0 it would be 5 more.
