We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

Results and Discussion Problem: Identifying which liquid evaporates faster Hypothesis: Acetone evaporates faster than kerosene‚ water and alcohol. Conduct an Experiment: Get .3 mL of each liquid Observe it for 3 minutes until it evaporates Gathering Data: Kerosene = 2 minutes and 3 seconds Water = 3 minutes and above Acetone = 1 minute and 22 seconds Alcohol = 1 minute and 52 seconds Conclusion: Acetone is evaporates faster than the other liquids such as alcohol‚ kerosene and

As with Lard none of the liquid dissolved with it. Adding the soap to the solids also didn’t dissolve anything. For the second station‚ Acetone had the lowest boiling point with 60 °C‚ then Hexane with 62 °C‚ Ethanol with 80 °C and lastly Water with the highest boiling point of 85 °C. For the third station‚ with the highest and lowest viscous‚ Hexan had the lowest viscous of 2.03‚ third was

Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas Test. This was conducted to classify the samples from being a primary alcohol‚ a secondary

INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on differences

You will test nine substrates (Figure 1) under each of these two reaction conditions to see which compounds will do SN1‚ SN2‚ neither reaction or both. You will observe the formation of a precipitate upon reaction. For the SN2 reaction‚ NaI is soluble in acetone but the byproducts of reaction‚ NaCl or NaBr (depending on the leaving group of each compound) are not. For the

During the lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical
