Answer:
None of the options are correct.
The answer to the question is 5.01x10^-3M
Explanation:
The following were obtained from the question:
pH = 11.7
Recall: pH + pOH = 14
11.7 + pOH = 14
pOH = 14 — 11.7
pOH = 2.3
Now we can obtain the [OH^-1] as follows:
pOH = —Log [OH^-1]
pOH = 2.3
2.3 = —Log [OH^-1]
—2.3 = Log [OH^-1]
Take the anti-log of —2.3
[OH^-1] = 5.01x10^-3M
