@ pH 7
--> [H+] = 100 nmol/L
@ pH 7.36
--> [H+] = 44 nmol/L
@ pH 7.4
--> [H+] = 40 nmol/L
@ pH 7.44
--> [H+] = 36 nmol/L
Thus,
--> Almost all [H+] at all pHs can be estimated
For example,
@ pH 7.1
[H+] = 80 nmol/L (40x2)
@ pH 6.8
[H+] = 160 nmol/L (80x2)
@ pH 7.3
[H+] = 50 nmol/L (100/2)
Thus, it can be estimated
