Experiment #: 7 Title: Organic Synthesis Purpose: The purpose of this lab was to determine the process of synthesizing various carboncontaining organic products including aspirin, urea, & salicylic acid. In doing so, we were also able to calculate the percent yield in each of these experiments. Procedure: Part 1: Synthesis of aspirin 1. Placed 2.0 g of salicylic acid & placed it in a flask 2. 5.0 mL of acetic anhydride was then added to the flask & mixed 3. 5 drops of sulfuric acid was a...

Florida CHM 2210L Simple and Fractional Distillation of a Binary Mixture Post-Lab Report 2024 Complete What is distillation? separation of liquids based on boiling point differences Explain the procedure in simple/fractional distillation 1. Set-up the simple/fractional distillation apparatus - heat source (hot plate or bunsen burner + wire gauze), distilling flask, column, condenser, receiving flask 2. Place 20 mL n-hexane + 20 mL toluene in 100 mL round bottom flask 3. Start distilla...

BTEC Level 3 Applied Science Unit 2 LAB. BTEC Level 3 Applied Science Unit 2: Practical Scientific Procedures and Techniques Learning Aim B: Undertake calorimetry to study cooling curves Introduction The aim of this practical is that we are trying to contrast the rate of cooling between stearic acid and paraffin wax. Both paraffin wax and stearic acid have the same forces of attraction between them. The higher the temperature, the higher the kinetic energy of these molecules and the faster...

Standard - A document, the main text of which contains only mandatory provisions using the word "shall" to indicate requirements and that is in the form generally suitable for mandatory reference by another standard or code or for adoption into law. Nonmandatory provisions shall be located in an appendix or annex, footnote, or fine print note and are not to be considered a part of the requirments. Guide - A document that is advisory or informative in nature and that contains only nonm...

BTEC Level 3 Applied Science Unit 2 LAB. The aim of this practical is that we are trying to contrast the rate of cooling between stearic acid and paraffin wax. Both paraffin wax and stearic acid have the same forces of attraction between them. The higher the temperature, the higher the kinetic energy of these molecules and the faster they move around and as the molecules move slower, the forces of attraction will be greater as they will be forming bonds. I will be calibrating the thermometer...
