If the [H+] concentration is 1*10^-4 then the pH =4 b/c -log(10^-4) = 4.

And pH + pOH = 14 at STP. So therefore, if pH =4 then 14-4 = 10. The pOH = 10.

in traditional refrences PH+POH =14= P kw ; w: water
PH=-log [H]=-log(1*10-4)=4
i.e POH=14-4=10
note
recently after 1990 PKw~16 and had anew meaning
thank u for ur time
