CHM120H5 Lecture Notes - Hydrogen Peroxide, Aluminium Hydroxide, Thioacetamide
Document Summary
This lab was a qualitative lab and so the point was to indentify unknown compounds rather than trying to figure out the amounts of different compounds. The purpose of this experiment was to become familiar with some of the characteristic reactions of the four metal ions pb+2, Fe+3, al+3, cu+2, and to find out which of those metal ions were present in the provided unknown solution. The latter was done by performing the same tests on the given unknown solution and the given known solution concurrently, and then comparing the results. The known sample and unknown sample #538 were obtained and poured into test tubes which were labeled accordingly. They were mixed, centrifuged, and liquid and solid components were separated into different labeled test tubes. Water was added to the solids, they were boiled, and mixed, and k2cro4 was added to them. They were heated, and centrifuged so that the solids and liquids were separated.
