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.

Best ResponseYou've already chosen the best response.1\[[H30+][OH] = 1x10^14 at 25C \] \[pH = Log[H+] = \log[0.0006] = 3.22 \] \[1x10^14/[H3O+] = [OH] 1x10^14/(6x10^4) = (1.7x10^11) = pOH (1.7x10^11)(6x10^4) = 10^14

Best ResponseYou've already chosen the best response.1The 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

Best ResponseYou've already chosen the best response.0Ok 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?

Best ResponseYou've already chosen the best response.1Yeah 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.

Best ResponseYou've already chosen the best response.0Ok that totally makes sense (as if it wouldn't) Thank you for explaining that!! Feel kinda silly for even asking

Best ResponseYou've already chosen the best response.1Another thing is that your Kw will change depending on the temp, but they usually give you the one at 25*C.
