In the present article it is described the quantification of cyclobenzaprine, metformin, metoclopramide and ranitidine hydrochlorides in tablet formulations using silver nitrate as titrant and conductometric titration, as a suggestion for an experimental activity in graduate courses. The conductometric titration was applied for hydrochlorides determination in four tablet formulations and the results are in good accordance with the declared values of manufacturers, at a 95 % confidence level. The experimental activity is simple and low coast, which enables it to be used in experimental activities on teaching laboratories improve student learning.
