Identification of Metallic Ions Peter Jeschofnig‚ Ph.D. Version 42-0160-00-01 Kellie Long Purpose: To observe the different flames of alkali and alkaline metals. Procedure: Place a little bit of each element into the well plate. Then you soak a tip of a cotton swab in each solution. Then you place the cotton swab over the Bunsen burner until the flame changes color. observations The color of the flame is expected to be as follows: Metallic ion Flame color

composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification of the unknown component‚ as well as the true percent composition of each component of Panacetin. This experiment involves two parts‚ covering a few required techniques to be learned

In this experiment‚ the scientists will research and test which of the four substances is the most efficient at absorbing water in cucumbers. The independent variable is the different substances being used. The dependent variable in the experiment is the amount of water absorbed. There are many constants including the same brand of cucumber slices‚ the same amount of each substance applied‚ the same measuring tools being used‚ and the same observation time. The control of these scientists’ experiment

Stoichiometry Lab Stoichiometry is the end result of adding up chemical elements that were involved in chemical reactions (http://dictionary.reference.com/browse/stoichiometry). The word stoichiometry was obtained from two greek words meaning element and measure. This explains the definition for the term. A chemist named Jeremias Benjamin Richter was the chemist responsible for first realizing what stoichiometry was (http://www.chemteam.info/Stoichiometry/What-is-Stoichiometry.html). In 1972

Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:
