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 1.72×10−4 m koh. the gastric juice sample required 17.2 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



Answer :

The pH is found out to be 3.79

Ph calculation

What are pH and its composition?

A chemical solution’s pH value indicates how basic or acidic it is. A pH value of seven is regarded as neutral, less than seven is acidic, and more than seven is basic on the spectrum of 0 to 14.

The hydrogen ion concentration of a solution is represented by pH, which is the negative base-10 logarithm (“log” on a calculator).

How acidic is the water?

Water has a pH of 7, which is exactly in the middle of the pH scale, in its purest state.

The pH of water can be altered by particles, and the majority of usable water has a pH of between 6.5 and 8.5.
