Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise interfere with the titration.

I got 4.9 and it says it's incorrect. What did I do wrong?

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 4.95 × 10-4 M KOH. The
gastric juice sample required 4.58 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 =
Incorrect
4.9
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
unable to determine
yes

Expert Solution

Step 1: Acids and bases

Acids and bases are two chemical substances that react with each other to form a salt and water. Acids have a sour taste, while bases have a bitter taste. Acids turn litmus paper red, while bases turn litmus paper blue.

The pH scale is a measure of how acidic or basic a solution is. The pH scale ranges from 0 to 14, with 7 being neutral. Solutions with a pH below 7 are acidic, while solutions with a pH above 7 are basic.
