Experiment 42: Ferrocene Preparation Introduction: The purpose of the lab is to prepare ferrocene from ferrous chloride and cyclopentadiene. Ferrocene‚ an organometallic‚ is a combination of two cyclopentadienide ions with a ferrous cation‚ such that the six pi electrons binds every carbon equally to the metal forming a sandwich type structure. Ferrocene has the properties of both an activated benzene (undergoes electrophilic substitution reactions) and a ferrous ion (oxidation reaction). Glyme

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

Abstract: This experimentation was to evaluate absorbance and the reaction rate of an enzyme‚ ’-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To

‚ saliva and hydrochloric acid was used in the second test. The enzyme involed in this test is salivary amylase which can found in saliva. Salivary Amylase‚ is called ptyalin it’s to break down starch to sugar. Things we ate is broken down in mouth by amylase. Amylase hydrolysed starch into a reducing sugar which can give beneduct test a positive result. Body temperature is the optimal temperature for the action of amylase. Enzymes are catalysts for any reactions. They provide an alternative way

Lactase is an enzyme that splits up the disaccharide lactose into monosaccharides glucose and galactose‚ but its function diminishes with age resulting in a wide use of lactase supplements. This enzyme functions under specific conditions‚ so we investigated the effect different salt concentrations have on the enzyme activity. Serial dilutions were performed to prepare a lactase solution as well as twenty percent‚ fifteen percent‚ and five percent concentrations of NaCl. Three different treatments

INTRODUCTION: An enzyme is a substance that in most situations‚ is a catalyst‚ which increases the rate of reaction by contributing alternative reaction pathways of lower activation energy. Enzymes are able to do this by binding to reactant molecules and allowing them to cooperate in a more energy efficient way. If catalyzed by the appropriate enzyme‚ reactions that would take an extreme amount of time would rather occur in fractions of a second. First‚ enzymes increase the rate at which chemical
