A gravimetric analysis was preformed on an unknown chloride sample in the laboratory to try and determine the identity of the solid. if the results of the experiment were 32.52%, 32.14%, 32.61 and 41.29 what is the mean, standard deviation and relative standard deviation of these experiments? finally, can any of these results be discarded and if so why?

Experiment: Sodium Content in butter Intro: An experiment conducted to determine that amount of sodium in butter through back titration of measuring chloride ions. the chloride ions themselves are not directly titrated ; rather a known excess of silver nitrate is added to the sample. A silver chloride precipitate immediately forms leaving behind the excess silver ions. the leftover silver ions are then titrated with ammonium thiocyanate forming a silver thiocyanate precipitate. Based on the amount of ammonium thiocyanate consumed,...

Calculate the maximum mass (in g) of AgCI lost in a chloride analysis as a result of washing the of silver chloride with 122 mL of water at room temperature. (Note: Ksp for silver chloride is 0.000000000160. Pay attention to the sig.fig. in your calculation. Keep three sig figs. In the answer.) Answer:

Question 1 A Chem 2111 student in a gravimetric analysis experiment analyzed an iron ore by dissolving a 1.1234 g sample in concentrated HCl solution. After dilution with water, the iron(III) in the sample was precipitated as Fe2O3.xH2O by addition of ammonia NH3. After filtration, washing and drying, the precipitate was isolated to produce 0.5394 g of pure Fe2O3. a) Calculate the weight percent of iron Fe in this sample. b) Calculate the weight percent of magnetite Fe3O4 (rock mineral)...

As part of a soil analysis on a plot of land, a scientist wants to determine the ammonium content using gravimetric analysis with sodium tetraphenylborate, Na*B(C,H,7. Unfortunately, the amount of potassium, which also precipitates with sodium tetraphenylborate, is non-negligible and must be accounted for in the analysis. Assume that all potassium in the soil is present as K2CO3 and all ammonium is present as NH4CI A 5.075 g soil sample was dissolved to give 0.500 L of solution. A 100.0...
