2 During the separation of a mixture of benzoic acid, salt, and sand, a student records the following results. (6 pts) A. Complete the following table: Trial Unknown mixture (a) 4.9648 g Filter paper for sand 0.8120 g 2.4115 g Filter paper dried sand Empty beaker for salt 126.5215 g Beaker +evaporated salt 129.0819 g Filter paper for benzoic acid 0.2755 g Filter paper+ dried benzoic acid 1.3780 g Mass Sand (b) Mass Salt (e) Mass Benzoic acid...
Question # 9 (9 pt) In the lab you performed to determine the % of salt in a mixture of salt and sand. a. Which part of the procedure was performed with the aim of separating the salt from b. Which part of the procedure was performed with the aim of collecting all of the salt c. Which part of the procedure was performed with the aim of finally getting a measure nothing but the salt? of salt and Choose...
When separating Sand from Salt in a mixture during an experiment, why would you need to add water to the salt twice when seperating the salt?
A student obtains an unknown mixture of copper sulfate and sand from the Stockroom Window, and carries out the procedure for Experiment 2 carefully as written. The student obtains the following data: Part A Mass of unknown sample and test tube: 9.1589 g Mass of test tube: 7.8965 g Part B Mass of Filter Paper: 0.6127 g Mass of Watch Glass: 6.9548 g Combined Mass of Watch Glass, Filter Paper, and Sand: 7.879 g Calculate the Mass % of Sand...

4. a. A sample of a CaCI 2HO/K C,0, HO solid salt mixture is dissolved in -150 mL of deionized water previously adjusted to a pH that is basic. The precipitate, after having been filtered, was air-dried and weighed. Data for Trial I were obtained as shown. Complete the following table. (See Report Sheet.) Record calculated values with the cor- rect number of significant figures. A. Precipitation of CaC,0,H from the Calculation Zone Salt Mixture 3. Mass of salt mixture...

INTRODUCTION Most of the matter around us con combination of two or more Mixtures have the following fundamental proper natter around us consists of mixtures of different substances. A mixture results from the tivo or more pure substances, elements or compounds that do not react chemically. • Each component of...
Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
