Andrew Li Chemistry 127 Professor Beaton Due March 15 2018 The Chemistry and Qualitative Analysis of Cations: Group Separations and Separation of Group I Cations Purpose: In this experiment, we were to precipitate group I cations such as Silver(I), Mercury(I), and Lead(I). We obtained both a known and an unknown mixture in order to detect the presence of different Group (I) cations. Also this lab taught us how to use a centrifuge to separate the liquid component of the mixture and the solid component. Fundamental Principle or Theory Behind the Experiment: The major principle behind this experiment was precipitation and learning how to use different chemicals to precipitate the Group 1 Cations. Precipitate is usually in some sort of solid form and is the product of a reaction. In order to study the precipitate we need to be able to extract it from the rest of the mixture. This brings about another principle which is very major to this experiment. In this experiment, we discuss and incorporate the use of a centrifuge. Using a centrifuge we were able
