Re: pH to [H+]
Here are all the formulas I have for switching from pOH to pH, hopefully they help.
pH=-log[H3O+]
[H3O+]=10^(-pH)
pOH=-log[OH-]
[OH-]=10^(-pOH)
pH+pOH=14
[H+]=10^(-pH)
pH=-log[H3O+]
[H3O+]=10^(-pH)
pOH=-log[OH-]
[OH-]=10^(-pOH)
pH+pOH=14
[H+]=10^(-pH)

Re: pH to [H+]
pH = -log[H+]
because of this, we can also say that:
[H+] = 10^-pH
we also know that:
pOH = -log[OH-] (because [H+]*[OH-]=10^-14).
so we can say that:
[OH-] = 10^-pOH
however if you want it using pH, since we know that pH + pOH =14, it would be: [OH-] = 10^-(14-pH)
because of this, we can also say that:
[H+] = 10^-pH
we also know that:
pOH = -log[OH-] (because [H+]*[OH-]=10^-14).
so we can say that:
[OH-] = 10^-pOH
however if you want it using pH, since we know that pH + pOH =14, it would be: [OH-] = 10^-(14-pH)

Re: pH to [H+]
The way to calculate the concentration of Hydrogen ion in solution when given the pH is to take 10 and raise it to the -pH power. Ex: if the pH of a solution is 1 the [H+] would be 10^-1=0.1M.

Re: pH to [H+]
To go from pH to [H+] you just need to work backwards. Because we know the formula for pH = -log[H+], we can rearrange the terms to solve for [H+] which gives us [H+]= 10^(-pH)

Re: pH to [H+]
Hi! Here are the formulas for converting from the different values:
-log[H3O+] = pH
-log[OH-] = pOH
pH + pOH = 14
[pH][pOH] = 10^-14
-log[H3O+] = pH
-log[OH-] = pOH
pH + pOH = 14
[pH][pOH] = 10^-14

Re: pH to [H+]
To find [H+] from the pH equation, you must simply undo the pH equation. pH=-log[H+]. In other words, to rearrange the equation to get [H+], you would undo the base 10 logarithm and get 10^-pH=[H+]. You can do this same process to find [OH-] from the pOH equation.

Re: pH to [H+]
To go from pH to [H+], you would do 1*10^-pH and to go from [H+] to pH, you would do -log([H+]).

Re: pH to [H+]
The formulas to go back and forth from pH to [H+] are: [H+]=10^(-pH) and pH=-log[H+].

Hi,
The formula is . I find this graphic helpful when trying to remember and figure out which conversions to use depending on the context.

Re: pH to [H+]
The formula is [H] = 10^-pH. With that being said, to find [OH], the formula is [OH] = 10^-pOH. Hope this helps!

Re: pH to [H+]
To convert pH to [H+], use the formula pH= 10^-pH. Some scientific calculators actually show this as the inverse calculation!

Re: pH to [H+]
To pH to [H+], you want to use the formula 10^-pH=[H+]. It also works for the [OH-] to pOH conversion as well.

Re: pH to [H+]
to go from pH to [H+] the equation is:
[H+] = 10^-pH
similarly, to convert from pOH to [OH-]:
[OH-] = 10^-pOH
[H+] = 10^-pH
similarly, to convert from pOH to [OH-]:
[OH-] = 10^-pOH
Re: pH to [H+]
Anything with a p in front of it means take the -log. PH is the -log of the concentration of hydronium ions.
