Answer:
The answer is
[OH-] = 1.66 × 10^-14 M
Explanation:
To find the [OH-] we must first find the pH and the pOH of the solution
That's
pH + pOH = 14
pOH = 14 - pH
To find the pH we use the formula
pH = -log [H3O+]
From the question
[H3O+] = 0.6 M
pH = - log 0.6
pH = 0.22
pOH = 14 - 0.22
pOH = 13.78
We can now find the [OH -] in the solution using the formula
pOH = - log [OH-]
13.78 = - log [OH-]
Find the antilog of both sides
We have the final answer as
[OH-] = 1.66 × 10^-14 M
Hope this helps you
