18. Aqueous Equilibrium
Titrations: Strong Acid-Strong Base
26PRACTICE PROBLEM
A condition know as hypochloridia occurs when there is an insufficient amount of acid in the stomach. To diagnose this condition, a sample of the gastric juice is collected (after fasting) and titrated against KOH to calculate the pH of the sample.
A) If a 10.0 mL sample of gastric juice required 25.8 mL of 0.000358 M KOH solution for titration, calculate the pH of the gastric juice sample.
B) For a positive diagnosis of hypochloridia, the pH of the sample must be greater than 4. Does the patient suffer from hypochloridia?
