Gravimetric Analyis Report

**This laboratory was performed in a first year actor Chemistry class *Note that data presented here be solo references to YOUR actual experiment. Dont desex 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 soluble salinity through a precipitation reception. Theory hydrometric analysis is a technique in which the specific ion nether 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 comp letion. Although AgCl(s) is very insoluble, it does non loaded that it is completely insoluble (Burk, 2008). This small amount of solvability rotter 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 ascendent with the Cl-(aq) ion, the added Ag+(aq) precipitates readily a s AgCl(s) until all of the Cl-(aq) is consum! ed. up to now if the reaction goes to completion, there is cool off 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 cartridge clip 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: BestEssayCheap.com
