H+ concentration? (1 Viewer)

[bEAbEA]

how you calculate [H+] ion concentration if you are given a pH. Eg. what is the [H+] when the pH is 4.63?

 

[serge]

inverse log10 button minus whatever pH is given

press shift
press log
type in the pH
press the +/- button

thankyou

 

[sikeveo]

press shift
press log
type in the pH
press the +/- button

dont u have to also minus whatever ph is given, like serge said?

you're right

you press the +/- button before u type the pH
(actually on some calculators it wont matter)

 

[annie_sinc]

not sure how u do it on ur calculator, but that's how i do it on mine

10^(-pH)

10^(-4.63) = 2.3 X 10^-5

calculating the pH also depends on whether the substance is monoprotic, diprotic or polyprotic. make sure you know and use that, because then the pH will be wrong.

and it has to be a strong acid for the calculation to be correct
