laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure Exercise #1 Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot using the data. Step #2: Determine the concentration of M of the samples in table 2: A=ebc A= 2-log(%t)

In recent history the black colour comes from an aniline dye. The next recipe indicates that nigrosene (generically‚ a black dye made from oxidised aniline) was domestically procurable in the 1940s. Note that the above recipe uses potassium carbonate (potash) whereas the following recipe uses potassium bicarbonate‚ which is not potash. Imperial

Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography‚ a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action‚ the. components

Cockroaches and Hemolymph Concentration in the Body Abstract This lab was conducted to determine the concentration of hemolymph in the body of a cockroach. It was done by making serial dilutions to make a standard graph by injecting a dye into a cockroach and determining the concentration at different times with the use of a spectrophotometer to find the optical density which is measured in absorbance. Results showed that the concentration was not within the pre-experiment research range

Coconut Water Wax A Breakthrough in Fruit Preservation ABSTRACT This study utilized coconut water to produce a wax preservative for fruit and other foodstuff. Different fresh fruits were collected and assigned to four different treatments: * Treatment I (Control): fresh fruits without anything done * Treatment 2: fruits soaked in coconut water for 10 minutes * Treatment 3: fruits covered with coconut water wax * Treatment 4: refrigerated fruits The fruits used were oranges
