The Cation Experiment (Exp. 16) is a general chemistry “rite of passage”. It is an integral part of the general chemistry curriculum all over the world. In this qualitative analysis of an unknown sample, you will be asked to determine the presence or absence of sixteen cations in a “virtual unknown”. It is the kind of training that requires … Read more

Student outcome In this experiment we’re trying to find the concentration of the active ingredient for a households with sodium hypochlorite. The experiment carried out is a titration by using a known solution of hydrochloric acid. The equation we need to use is the CaVa=CbVb, where the C are the concentrations of the acid and base respectively, and the V are the volumes of them using in thetritation. In this experiment we have to solve for Cb, so we need to take a defined volume of sodium hypochlorite solution and add a known solution drop by drop of HCl, for example 1.00M and record how much volume of this was used in the tritation.
