The concentration of HCl in the stomach can be calculated using the formula pH = -log[H+]. Given that the pH of normal gastric juice is about 2, we can calculate the concentration of HCl as follows:
pH = -log[H+]
2 = -log[H+]
-2 = log[H+]
[H+] = 10^-2
[H+] = 0.01 mol/L
Therefore, the concentration of HCl in the stomach is about 0.01 mol/L.
4. Normal gastric juice has a pH of about 2. Assuming that normal gastric juice is primarily aqueous HCl, what is the concentration of HCl in the stomach?
