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 18.00 mL sample of her gastric juices and titrate the sample with 3.94 x 10-4 M KOH. The gastric juice sample required 6.60 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 titration. pH = Enter numeric value For the patient to be suffering from hypochloridia, the pH of the gastric juices from the stomach must be greater than pH 4. Does the patient have hypochloridia? (no O unable to determine yes

- 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 18.00 mL sample of her gastric juices and titrate the sample with 4.85 × 10-4 M KOH. The gastric juice sample required 1.26 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 titration. pH = For the patient to be suffering from hypochloridia, the pH of the gastric juices from the stomach must be greater than pH 4. Does the patient have hypochloridia? unable to determine no yesIn a hospital laboratory, a 10.0 mL sample of gastric juice, obtained several hours after a meal, was titrated with 0.01 M NaOH to neutral pH of 7.0; 72.0 mL of NaOH was required for this titration. The patient’s stomach contained no ingested food or drink, thus assume that no buffers were present. What was the pH of the 10.0 mL gastric juice sample before titrating with NaOH?A sample was analysed for renal and liver function tests. The sample was from a 50-year- old man who had seen his GP to report problems with tiredness.
