Chemistry A technician in a hospital laboratory obtained a 5.0 mL sample of gastric juice taken from a patient several hours after a meal and titrated the juice with 0.4 M NaOH to neutrality. The neutralization of gastric HCI required 6.4 mL of NaOH. The patient's stomach contained no ingested food or drink at the time of sample harvest. Therefore, assume that no buffers were present.

Concept explainers

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Chemistry
A technician in a hospital laboratory obtained
a 5.0 mL sample of gastric juice taken from a
patient several hours after a meal and titrated
the juice with 0.4 M NaOH to neutrality. The
neutralization of gastric HCI required 6.4 mL
of NaOH. The patient's stomach contained no
ingested food or drink at the time of sample
harvest. Therefore, assume that no buffers
were present.
What was the pH of the gastric juice?

A student was required to prepare 250.0 mL of a cyanoacetic acid/sodium cyanoacetate buffer in which the concentration of the weak acid component was 0.06 M and the concentration of the conjugate base was 0.028 M. The student was supplied with 0.512 M cyanoacetic acid and 1.0M NaOH to perform this task. What volume (in mL) of the acid would the student need to prepare this buffer solution? Hint: assume that all of the conjugate base comes directly from the reaction of NaOH with the weak acid (in other words, there is negligible dissociation of the weak acid). Please enter answers with 2 decimal places.

You have an unknown solution whose initial pH is 2.90. Addition of 10 ml of the titrant increased the pH to 4.15. Adding small-volume increments of the titrant causes the pH to increase very slightly. At equivalence point, the pH of the solution is at 8.70. Abrupt increase in pH to 10.00 was observed when 0.1 ml of titrant was added after equivalence point. Addition of few more drops of the titrant just increase the pH even more with no buffering region. Which among the choices best describes the analyte? The analyte is a strong monoprotic acid. The analyte is a weak monoprotic acid. The analyte is a weak monoprotic base. O The analyte is a weak diprotic acid. O The analyte is a weak diprotic base.
