[From: ] [author: ] [Date: 12-04-30] [Hit: ]
....to find the answer but, i dont know how to plug it in my calculator to get the final answer.......
What is the pH of a solution if [OH–] = 2.3 x 10–5 M?

i know to use the formula pOH= -log(OH-].....to find the answer but, i don't know how to plug it in my calculator to get the final answer....can someone please explain it to me...thanks for your help!

Don't forget to use
pOH ≈ 14 − pH
to find the pH once you have pOH

Type in 0.000023
Hit log, then =
(Note this is log base 10 so if you have a ln button and a log button, use the log not the ln)
Then find the +/- button to change the sign.

(then subtract the answer from 14 to get pH, so)
Hit M+
cancel
type 14
hit -
press MR
then =
