PPT-LAB. S2: Spectrophotometric

Determination of Indomethacin Salicylic Acid Mixture Objectives Scan an absorbance spectrum using the spectrophotometer Deduce the dependence of the absorption coefficient on the wavelength. So as to obtain the optimal labeling scores the label propagation algorithm requires an inverse matrix which in curs the high computational cost of cn where and are the numbers of data points and labels respectively This paper proposes an ef64257 ci brPage 1br 29 Lab Equipment 8606 1623 Page 29 brPage 2br 30 Lab Equipment 8606 1623 Page 30 brPage 3br 31 Lab Equipment 8606 1623 Page 31 brPage 4br 32 Lab Equipment 8 Spectrophotometric techniques are used to measure the concentration of solutes in solution by measuring the amount of light that is absorbed by the solution in a cuvette placed in the spectrophotome 1 Lab 8.

Results of spectrophotometric titration of Fe with PhNO in toluene; (a) typical series of titration curves, isosbestic points: 334, 394, 425, 473, 540, 590 nm; (b) spectrum of (Fe)(PhNO) (b 2) Using the exact weight of sodium bicarbonate that you measured from the data table, determine the theoretical yield of sodium acetate? (Use . stoichiometry. ) . 3) We are not at STP, therefore to convert milliliters to grams; the density of acetic acid needs to be used. The density of acetic acid is, 1.05 g/. Why is starch agar used?. -To see if saliva was present and broke down the starch.. Positive control . –used to show what the change looks like. Negative control. – used to what no change looks like. Eight Golden Safety Rules. Keep backpacks, purses, books, and coats in designated areas only. i.e.: . no personal items on lab bench while doing lab work. . Exception with current set-up: Lab book.
