Exp 7 Graph. Graph Paper.This manual is the culmination of the efforts of many individuals. While some of the experiments are "classics", and appear in various forms in many Quantitative Analysis textbooks and laboratory manuals, much effort was expended to ensure that the experiments work well here at UC Davis and thus each experiment has been extensively tailored for our laboratory program.

We view this manual as one of continual modification, and often improvements arise from comments and criticisms. We thus encourage you to discuss ideas for improvements with your TA and instructor.

Introductory Details Experiments have been set up for students working in small groups. Be sure to have a work plan that makes efficient use of your time. Lengthy sample preparation procedures should be started early in the six hours assigned to a given experiment. The method involves linearly varying an electrode potential between two limits at a specific rate while monitoring the current that develops in an electrochemical cell under conditions where voltage is in excess of that predicted by the Nernst equation.

The most obvious advantage of HPLC over gravity liquid chromatography is that samples can be separated much more quickly. The experiment is an adaptation of "Pollution Police" by Profs. Lab 4: Molecular Fluorescence When a molecule absorbs a photon in the ultraviolet or visible UV VIS region - nman electronic transition occurs within the molecule.

This transition involves moving an electron from the singlet ground state to a singlet excited state. The ITD is a variation of a quadrupole mass spectrometer and is designed to function specifically as a GC detector. Due to the design variances of the ITD compared to a true quadrupole mass spectrometer, the ITD mass spectrum of an organic compound may not be identical but should be very similar to its classical electron impact EI mass spectrum.

Lab 6: Capillary Electrophoresis Electrophoresis is a class of separation techniques in which we separate analytes by their ability to move through a conductive medium—usually an aqueous buffer—in response to an applied electric field. Lab 7: Electrospray Mass Spectrometry In this experiment you will learn the mechanics of electrospray mass spectrometry and use this technique to study the effect of different solvents on the three-dimensional structure of proteins.

Contributors W. Fawcett, John Berg, P. Kelley, Carlito B.Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision.

A metric ruler will be used to measure length in centimeters cm. All measuring devices are subject to error, making it impossible to obtain exact measurements. Students will record all the digits of the measurement using the markings that we know exactly and one further digit that we estimate and call uncertain. The uncertain digit is our best estimate using the smallest unit of measurement given and estimating between two of these values.

These digits are collectively referred to as significant figures.

Note, the electronic balance is designed to register these values and the student should only record the value displayed. When making measurements, it is important to be as accurate and precise as possible. Accuracy is a measure of how close an experimental measurement is to the true, accepted value.

Precision refers to how close repeated measurements using the same device are to each other. The correct reading is 1. The first 2 digits 1. The last digit 1. You may have instead estimated it as 1.

General, Organic and Biological Chemistry Lab Manual

The measuring devices used in this lab may have different scale graduations than the ones shown Precision is basically how many significant figures you have in your measurement.

To find the precision, you basically take the smallest unit on your measuring device, and add a decimal place the uncertain digit. In general, the more decimal places provided by a device, the more precise th e measurement will be. Measurements obtained in lab will often be used in subsequent calculations to obtain other values of interest. Thus, it is important to consider the number of significant figures that should be recorded for such calculated values. If multiplying or dividing measured values, the result should be reported with the lowest number of significant figures used in the calculation.

If adding or subtracting measured values, the result should be reported with the lowest number of decimal places used in the calculation. Calculate his velocity or speed. If In this lab, students will also determine the density of water as well as aluminum.My Favorites List.
