Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

The Base Ball Pitch - Tom Hando The biomechanics of a movement is slightly different to the physiological principles of it. The biomechanics of a movement‚ is how the forces acting upon an object effects the way the object moves. (FIGURE 1) For example in my movement‚ the baseball pitch‚ in the wind up stage of the pitch‚ the forces acting upon the body is causing hip and knee flexion which results in the knee and hip coming into contact with the chest. Whereas the physiological principles is working

Exploring the acid content of Pepsi products Lab performed: February 27‚ 2012‚ March 12‚ 2012‚ and March 19‚ 2012 Purpose: The purpose of this experiment was to discover the unknown concentration of acid in six different Pepsi products; Pepsi‚ Diet Pepsi‚ Dr. Pepper‚ Diet Dr. Pepper‚ Pepsi Wild Cherry‚ and Pepsi Max. Titrations find the point at which equal moles of a known concentration react with equal moles of an unknown concentration giving the equivalence point. Also‚ the

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator
