c) How many times greater is the hydrogen ion concentration of the acidic stomach in part (b) than the lemon juice in part (a)?
This is a pretty simple division problem, now that we’ve done all the hard work in parts (a) and (b).
Stomach [H+] = 0.1M
Lemon [H+] = 0.00501 M
So the ratio of hydrogen ion concentration in the stomach to that in the lemon is:
(0.1 M) / (0.00501 M) = 19.9526… or ~20.0 times more acidic.
That’s pretty acidic…
