Answer:
[OH-] = 10^(-12) M
Explanation:
pH + pOH = 14
2.0 + pOH = 14
pOH = 12.0
pOH = - log[OH]
12 = - log[OH-]
[OH-] = 10^(-12) M
The concentration of hydroxyl ion will be [tex]10^{-12} M[/tex] by using the pH formula.
The pH scale, which previously stood for "potential of hydrogen," would be used to describe how acidic or basic an aqueous solution appears.
The pH can be expressed by the formula:
pH + pOH = 14
2 + pOH = 14
pOH = 14-2
pOH = 12.
Now, use the formula:
pOH = -log[OH]
12 = -log[OH]
[OH] = [tex]10^{-12} M[/tex]
Therefore, the concentration of hydroxyl ion will be [tex]10^{-12} M[/tex].
