Gravimetric Analysis of SULFATE as Barium Sulfate. Objectives * To learn the techniques associated with gravimetric analysis. * To use stoichiometry to calculate the percentage by mass of sulfate in an unknown sulfate salt. Background Gravimetric analysis is a quantitative method for accurately determining the amount of a substance by selective precipitation of the substance from an aqueous solution. The precipitate is separated from the remaining aqueous solution by filtration and

Punjabi February 16‚ 2017 RESULTS & DISCUSSION The purpose of this experiment was to utilize two different methods of qualitative analysis to determine the identity of two unknown cations in an unknown solution. The experiment required knowledge of solubility rules and demonstration of such in the laboratory setting for the first method of qualitative analysis. The second method of qualitative analysis was the performance of a flame test on various solutions to prove the presence of certain ions based

possible substances. Theory Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing. We suspect that this unknown compound is either acetanilide or phenacetin. From the solubility of acetaminophen and phenacetin‚ we could know both of them are relatively soluble in boiling water but insoluble in cold water so that we took the recrystallization as the method to purifying the unknown component. After the unknown purified‚ then

Resolution of Matter into Pure Substances – Paper Chromatography Abstract The purpose of this laboratory was to determine how different substances have different solubilities in a given solvent. This was accomplished using the method of chromatography. The solubility of each substance was first determined by dropping a drop or two of each on a line drawn 2 inches above the bottom of a piece of paper. Then the paper was lightly bent in order to tape both sides of the paper leaving about a 4 centimeter

Most reactions produce a crude mixture of undesired reagent‚ byproducts‚ as well as the desired product. Extraction allows for the separation of a compound from a complex mixture. The different components can be eliminated by their different solubilities. Ultimately‚ through a simple distillation and filtration process‚ crystals of the desired product can be achieved.

SPOTTING EFFECT Specific Objective: Test for the presence of lipids by means of locating translucent spots/area in the filter paper. B. SOLUBILITY Specific Objective: To test for the solubility of the suspected lipid-containing samples. C. TEST FOR UNSATURATION (BROMINE WATER TEST) Specific Objective: To test for unsaturation of lipids through a change in colour or discoloration of the bromine water. To test

benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis is that a new substance will form. Net reaction: C6H5COONa(aq) + HCl(aq) C6H5COOH(s) + NaCl(aq) Upon completion of this experiment students will gain experience using common extraction techniques such
