Experiment 8: Identification of an Adulterated Herb The purpose of this lab is to analyze the volatile oils of some herbs through TLC testing and then identify the adulterant in a sample. Unfortunately‚ we ran out of time to complete the lab; however‚ we were able to get through most of it‚ and were only missing the adulterant. The first step to identify our unknown samples was to create TLC plates that should results with each known compound and 95% hexane: 5% ethyl acetate‚ 90% hexane: 10%

to find out how much acid was needed to neutralize two tablets of TUMS. In the first process of the titration‚ we added excess HCl and then we had to back titrate it by adding NaOH. We had to do a standardization test because the NaOH has a high reactivity and that could cause a small change. The NaOH solution was supposed to have a molar concentration of .5 however when we standardized the solution we found the actual molarity of the solution to be .4761. This may be due to the fact that NaOH is

magnesium hydroxide (Mg(OH)2)‚ and this coating will prevent further reaction. Therefore‚ in the heater meal‚ iron is added to the magnesium‚ leading to the production of a local cell – small-scale corrosion that happens where two metals of different reactivity are in contact under humid conditions – which speeds up the exothermic reaction. Because the electron potential of magnesium is lower than that of iron (the less reactive metal)‚ electrons will pass from the magnesium to the iron‚ and only from
