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,...

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)...
