  • Ochem Lab Benzophenone

    Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment, we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface...

    Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes, and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points, or that have one component that does not distill. There are many types of distillation, each of which has a distinct...

    Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature, some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However, the excited configuration is unstable, and the electrons must return back to their positions in the lower energy level. As they return, the energy that was previously absorbed is now emitted...

     Lab Report: Scientific Method Your Name: Taylah Harness Purpose of this Lab What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain? The goal for this lab is to be able to get the boiling water's temperature to increase by adding table salt. The problem it is trying to explain is, how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the...

    Kevin Johnson Lab 1 Safety Quiz 1. List three (3) unsafe activities in the illustration and explain why each is unsafe. Ayanna is not wearing safety goggles: It is unsafe because eyes are vulnerable to chemical spills and splashes, shattered rocks and glass, and floating and flying objects. Lindsey’s long hair is waving around: It is unsafe because hair, clothing, and jewelry can create hazards, cause spills, and catch fire while experimenting. Always tie or pin back long hair. Chris...

  • PRE LAB

    Pre-Lab Work Sheet Which type of compound usually has higher melting points: ionic compounds or covalent compounds? What is the reason for this difference in melting points? (3 points) Ionic compounds have higher melting and boiling points than covalent compounds. The electrostatic attraction in an ionic bond is very strong hence a lot of heat energy is required to break it down, ionic bonds have high melting and boiling points. In covalent bonds, the intermolecular forces are very weak and...
