points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance‚ then plotting heating and cooling curves and analyzing them. Data that you collect will represent the

this recrystallization lab in order to achieve the desired results‚ which included heating the solvent‚ completing a hot filtration‚ completing a vacuum filtration of a chilled solution‚ as well as drying and calculating the weight and melting point of the final version of the sample. I began the lab with 1.5 grams of the impure acetanilide solute and ended the lab with 0.05 grams of pure acetanilide crystals. The percentage of pure acetanilide I recovered during this lab was 3.33%‚ which is lower

Krupa Desai Cell Biology April 3‚ 2013 Lab: Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test

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

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

Mirror Lab One air inhalation hazard I observed during the Mirror Lab tour was for rhodite 906. In a large open room and workspace‚ the mirror lab utilized rhodite frequently to polish large new mirrors. This is concerning because this is a hazardous dust particle with its particle size at about 1.5 micrometers. The movement of these particles are heighted by water mist placed above the mirror to keep the rhodite from solidifying. The employees also sprayed down the mirror frequently which further

Abstract: All the materials were measured and weighed. It was found in the experiment that the yield of copper hydroxide in 40%. Introduction: The copper (II) sulphate is then placed in 100 mL of distilled water. Then 20 mL of CuSO4 is measured and placed 100 mL of distilled water. This can later be weighed to determine the mol of CuSO4 and the mol/L concentration. Then this was used to find out how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II)
