Researchers used gas chromatography to determine the % v/v methyl salicylate in rubbing alcohol [Van Atta, R. E.; Van Atta, R. L. J. Chem. Educ. 1980, 57, 230-231]. A set of standard additions was prepared by transferring 20.00 mL of rubbing alcohol to separate 25 - mL volumetric flasks and pipeting 0.00 mL, 0.20 mL, and 0.50 mL of methyl salicylate to the flasks. All three flasks were diluted to volume using isopropanol. Analysis of the three samples gave peak heights for methyl salicylate of 57.00 mm, 88.5 mm, and 132.5 mm, respectively. Determine the % v/v methyl salicylate in the rubbing alcohol.
GRAVIMETRIC ANALYSIS The addition of dimethylglyoxime, H2C4H602N2, to a solution containing nickel(Il) ion gives rise to a precipitate: Nickel dimethylglyoxime is a bulky precipitate that is inconvenient to manipulate in amounts greater than 135 mg. The amount of nickel in a type of permanent-magnet alloy ranges between 22% and 38%. Calculate the sample size that should not be exceeded when analyzing these alloys for a nickel.

(c) Why is a different conclusion drawn from using the paired i test than from just pooling the data and using the normal i test for differences in means?
(a) In High Performance Liquid Chromatography (HPLC), the separation method is by partition of the solute (analyte) between the mobile phase and the stationary phase. Explain how this leads to separation of analyte mixtures; (b) Describe the structure and materials use in a typical column used for HPLC. Thereby explain why high pressures have to be used in HPLC; (c) Discuss how the need for high pressures also imposes requirements on the injector;

A simple paper chromatography experiment involved the analysis of the food dyes in lollipop samples. A chocolate-flavored lollipop was dissolved using various solvents and was spotted in the chromatogram (E). Four food dye standards (blue, green, red, and orange) were tested alongside the chocolate-flavored lollipop. The mobile phase used for the analysis was 0.1% NaCl. After the analysis, the resulting chromatogram revealed the separation of three colors, which were attributed to the food dyes indigo carmine (blue), tartrazine (yellow), and erythrosine (red). 10 Ruler is in cm unit в с B C D A E A E BEFORE AFTER Calculate the rf for each dye.
