In the organic chemistry lab course there are two types of reports, which are all graded on a 100 point scale. One type comprises what’s commonly known as “lab reports,” that is, records referring to experiments performed in the lab. The other type refers to special assignments that are completed outside the laboratory. The format and contents of special assignments depends on their nature. They are specified in the syllabus, or at the time the assignment is made. Examples are the MSDS assignment in organic lab I, or the Chemical Literature assignments in organic lab II. Lab reports, on the other hand, have a set format. They can be or two kinds, depending on whether they refer to experiments involving physical operations or chemical preparations (synthesis).
LAB REPORTS FOR PHYSICAL OPERATIONS, OR TECHNIQUE EXPERIMENTS
This type of report refers to lab work whose main objective is to learn, demonstrate, or perform a physical operation. Physical operations do not change the chemical nature of the substances involved. They are typically conducted as part of a synthesis and are frequently of two types:
1. Purification techniques, or separations. These operations are designed to isolate a pure substance from a mixture. Examples are crystallization, extraction, and distillation.
2. Characterization techniques. These operations are designed to return information that can be used to identify a substance. Examples are the determination of physical constants such as melting point, boiling point, or density, and instrumental techniques such as infrared (IR) spectroscopy. Sometimes these techniques are referred to as analytical techniques.
LAB REPORTS FOR CHEMICAL PREPARATIONS, OR SYNTHESIS
This type of report refers to experiments whose main goal is to prepare a pure substance from specific starting materials. This necessarily involves a chemical transformation, or reaction. In the simplest case, there is only one step. The starting materials are combined and a product forms. This product is isolated, purified, and characterized, producing the final outcome of the experiment. In a multistep synthesis, the product of the first step is used as a starting material in a second step, and so on, until a final product is obtained. No multistep syntheses are performed in organic lab I. Some two step syntheses are performed in organic lab II.

Matter undergoes three kinds of change: physical, chemical, and nuclear. While the composition of a chemical substance is not altered by physical changes (such as freezing and evaporation), chemical changes, or reactions, result in the formation of new substances when bonds are formed and/or broken. Some relatively simple but common types of ...

This chemical equation represents a decomposition reaction. This identification is based on the fact that the single reactant chemical compound breaks down into two different chemical substances that are different from the initial chemical substance
Observe Record observations of the reaction and products in the data table. (Turn off the Bunsen burner.) Analyze Complete the balanced chemical equation in the data table. Then, determine the type of reaction. Reaction 4: Heat Sodium Carbonate Prepare Use a small spatula to place about half of an inch of sodium carbonate in a clean, dry test tube.
In conclusion, these experiments provided valuable insights into various types of chemical reactions. Experiment A demonstrated both decomposition and synthesis reactions, with decomposition being endothermic and synthesis leading to the reformation of the original compound.
This lab is designed to challenge students to identify types of chemical reactions and distinguish between those that use safer, less hazardous chemicals and those that are more dangerous. Students will make a choice as to which reaction they will perform using the 12 Principles of Green Chemistry. They will ultimately learn the difference ...

A well-structured lab report is essential for documenting the experiment and showcasing the findings. The lab report for such an experiment typically includes several key sections that you must be prepared to complete effectively. Sections of a Lab Report. A proper lab report should consist of the following components:

Chemical reactions can be classified into three major types: precipitation, acid-base, and oxidation-reduction reactions. Precipitation reactions: These reactions occur when two solutions are mixed, resulting in the formation of an insoluble solid called a precipitate. An example is the reaction between silver nitrate and sodium chloride, which ...
