HClO4 is 100% dissociated.
pH = -log(H^+). For pOH, use
pH + pOH = pKw = 14
what are the pH and the pOH of 0.125M HCIO4?

hi DrBob222,
thanks for your help. I understand that part, but how do you solve it using only the molarity?

I think i figured it out, would the pH be .9?
Exactly. Good work.
Thank you so much! Another question, the directions say, Determine the [H3O] and [OH] of each of the following solutions.
Lime Juice, pH= 1.9
Kitchen Cleaner, pOH= 4.75
Tomato Juice, pH= 4.23
How do I do this?

pH = -log(H^+) and
pH + pOH = pKw = 14.
lime juice pH will give you H^+ (technically it is H3O^+)
If you know pOH, you can solve the other equation to obtain pH.
Also you can use
pOH = -log(H^+) OR you can use
(H^+)(OH^-) = Kw = 1E-14.
pH + pOH = pKw = 14.

Thank you so much! Not I don't think I will fail my test tomorrow!
