What is the OH^- if the pH is 3.2, H3O^+ is 0.0006 M and the pOH is 10.8? Please explain how you found.

\[[H30+][OH-] = 1x10^-14 at 25C \] \[pH = -Log[H+] = -\log[0.0006] = 3.22 \] \[1x10^-14/[H3O+] = [OH-] 1x10^-14/(6x10^-4) = (1.7x10^-11) = pOH (1.7x10^-11)(6x10^-4) = 10^-14

The pH+pOH = 14 we have 3.2+10.8 = 14 also the [H3O+][OH-] = 10^-14 at 25 degrees celsius we know that the pH = -log[H] so the -log[0.0006] = 3.2 so we take 0.0006 = [H3O+] and we divide this by 1.0x10^-14 to get the concentration of OH- ions. oh in the last line it's 1.0x10^-14

pOH = -Log[OH-]

Ok so the H3O and OH together equal 1*10^-14 so, we do what we do with pH and pOH only instead of subtracting the one you have by what they equal together it's dividing?

Yeah so if you find one you know the other one b/c the product of both = 1.0x10^-14 at 25C, of course if you change the temperature this value changes.

FYI it's called Kw

Ok that totally makes sense (as if it wouldn't) Thank you for explaining that!! Feel kinda silly for even asking
Photon336
  • Photon336
nah its' totally fine.. feel free to ask me anything

Another thing is that your Kw will change depending on the temp, but they usually give you the one at 25*C.
