Problem 10: Patient Prognosis

This resource, from the Royal Society of Chemistry, can be used to develop students’ skills and understanding of analytical techniques, transition metal complexes and colorimetry. It can also be used to develop their observational and analysis skills.

The students have been asked by a doctor to test a patient’s urine sample for presence of glucose and the concentration of salicyclic acid, as well as measuring the blood alcohol level. Using this information the students are asked to make a hypothesis as to the reason why the patient fainted.

With the gas chromatography (GC) traces provided students are to produce a calibration graph, which, along with the GC trace of the patient’s blood to determine the blood alcohol content of the patient.

Curriculum links: transition metal complexes, colorimetry, alcohols, carboxylic acids, esters, analytical techniques

Practical skills: dilution, colorimetry, observation skills, GC analysis
