Question 133243: The pH scale is a measure of acidity, which is related to the concentration of hydrogen ions in solution. The concentration of hydrogen ions is symbolized as [H+]. The equation for pH is: pH = -log[H+]. The pH range of human blood is between 7.35 and 7.45. Calculate this pH range in terms of [H+].

The equation for pH is: pH = -log[H+]. The pH range of human blood is between 7.35 and 7.45. Calculate this pH range in terms of [H+].
------------------------------------
If pH=7.35, 7.35 = -log[H+]
log[H+] = -7.35
H+ = 10^-7.35
H+ = 0.000000044668...
------------------------
If ph = 7.45
H+ = 10^-7.45
H+ = 0.000000035481...
-------------------------
0.000000035481... < H+ < 0.000000044668...
