A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has this condition, her doctors take a 20.00 mL sample of her gastric juices and titrate the sample with 2.38 x 10-4 M KOH. The gastric juice sample required 21.6 mL of the KOH titrant to neutralize it. Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise interfere with the...
