Gravimetric Analyis Report

**This laboratory was performed in a first year source Chemistry class *Note that data presented here be solo references to YOUR actual experiment. Dont make out your values mixed up! goal This laboratory experiment was conducted to convey the methods used in hydrometric analysis to determine the amount of chloride content in impairment of mass and percentage in an unknown water-soluble salinity through a precipitation chemical reaction. Theory gravimetric analysis is a technique in which the specific ion beneath experimentation, in this case, the chloride ion, is found out through quantitative measurements. It relies on lotvass the masses of two compounds containing the specific ion. (Yoder and Leber, 2007.) In this particular experiment, a specific amount of chloride ion is sickend by an addition of silver ion in an unknown soluble table salt. This reaction is carried out as follows: AgCl(s) is in truth insoluble, and it is assumed that the above reaction goes to completion. Although AgCl(s) is truly insoluble, it does non loaded that it is completely insoluble (Burk, 2008). This small amount of solvability idler be stated using the solubility product, Ksp as follows: Ksp = [Ag+(aq)]·[Cl-(aq)] = 1.

6 x 10-10 Since the given Ksp value is relatively low, it can be ignored, as it has little effect on the situation. In other words, it is negligible. In this particular experiment, since the reaction is assumed to go to completion, a precipitate forms. Specifically, when AgNO3(s) is added to the firmness of purpose with the Cl-(aq) ion, the added Ag+(aq) precipitates readily as AgCl(s) until all of! the Cl-(aq) is consumed. up to now if the reaction goes to completion, there is even-tempered some salt left wing in solution (Burke, 2008). The reaction of silver chloride with the unknown salt occurs very quickly. This reaction forces the silver chloride to precipitate into small particles since not enough magazine is given for it to precipitate into crystals. The solution is het and gently...If you want to get a full essay, order it on our website: OrderCustomPaper.com
