Then by filtering, iodide can be extracted which when combined with other substances can make an iodine tincture, that is a pharmaceutical product. * Can a single substance be isolated from a mixture? Yes a single substance can be isolated from the seaweed mixture by using methods such as filtration and evaporation. In our experiment we used filtration using a filter paper funnel to extract the iodide from the tincture. * What is this substance This substance is iodide Confidence Report The aim of extraction, is to separate a part of raw material, using a solvent such as water with heat.
Discussion & Conclusion In this experiment we learned how to synthesize the cyclohexene by dehydration of cyclohexanol. We procedure the first step where we have to mix the components. Then we heat the R.B.F with a fractionating column, distilled water. Then we obtained the layers, and we transferred the organic layer to a small, dry Erlenmeyer flask. We added anhydrous Sodium Sulfate as a drying agent.

Extraction and Purification of Components in an Analgesic Tablet November 2, 2014 My signature indicates that this document represents my own work. Excluding shared data, the information, thoughts, and ideas are my own, except indicated in the references. 1 Abstract: HPLC is a very important technique used today in many pharmaceutical fields. It helps separate the solutions. After extraction was performed on the tablet it was then ran through an HPLC test.
Hydrate Lab The purpose of this lab is to analyze the percent water in a crystalline hydrate and to indentify the hydrate from a list of possible unknowns. The solid hydrate will be heated to remove the water, and the percent can be found by measuring the mass of the solid before and after heating. The hydrate will be indentified by comparing the percent water in the hydrate with the percent water calculated for the possible unknown. Before the lab there are pre-lab questions: 1. Describe the three general safety rules for working with a Bunsen burner.
HYPOTHESIS : What is the Dependent Variable measured: ______________________________________ What is the Independent Variable used: __________________________________________ Predict the effect of each situation/solution on the heartbeat: Make a Hypothesis for each Cold Water Hot Water 1% Ethanol Sugar Water MATERIALS • 4 Daphnia in culture liquid (per table) • Transfer pipette • a clean depression slide • Compound microscope • a small container for “used” Daphnia PROCEDURE – follow below or the modify to YOUR teacher’s instructions Keep the light for your microscope OFF as much as possible to avoid overheating your Daphnia! 1. Using a clean pipette, carefully transfer a Daphnia and ONE drop of liquid onto a slide. Keep the drop small so that the Daphnia can’t swim out of your field of view. 2.
(With resistance) Air: with resistance, syringe A can still be pushed a little towards syringe B. this is because particles in air are spread out; there are room in between to particles. That is why when syringe A is pressed down, the particles compressed together tightly causing the syringe to move a little before the particles were impacted too tightly for the syringe to move Water: water particles are different from gas particles. Water has very little compressibility. Particles in water are much more compacted together, therefore giving no space for them to compress more. This is the reason why with resistance, syringe A will not move as the particles in water are as tightly compressed together as they can get.
Then you put the remaining liquid (neutral component mixture) through the suction filtration funnel to isolate the crystals. After 10-15 minutes, the crystals will be dry and you can weigh them and find their melting point. How is the neutral component of your 3-compound mixture isolated from the final methylene chloride solution? 16 of 22 4/16/12 9:15 PM StudyBlue Flashcard Printing of Lab Final 2211L UGA http://www.studyblue.com/servlet/printFlashcardDeck?deckId=...

Title and number: 1-31 Molecular Mass of a gas Lab report number 2 Purpose: The purpose for doing this lab is to learn how to measure gas by using volume and water. Also to proved whether Avogadro hypothesis is true or not by using these characteristics: mass, volume, pressure and temperature that will allow you to calculate the molecular mass of any gas. Principle: The new lab technique that we used is the displacement of water. We did this by putting water in a tank, placing the graduated cylinder in the water and get the opening end of the graduated cylinder in the water while letting the water to enter the cylinder without getting any bubbles in it, because having bubbles in the water would increase the error percentage of our results. Then, stand the cylinder upside down after measuring the lighters and then, placing the lighter near the cylinder while releasing butane into the cylinder.
Heats of Solution and Reaction Name: Cindy Hernandez Purpose: The purpose of this experiment is to decided if the chemical reactions are exothermic and endothermic. By finding the differences between each temperature. Overview: For this lab, we had three different chemicals involved NH4Cl, H2SO4, and NaOH. What we did with these chemicals was that we added water, except NaOH we added HCl, was that we combined both mixtures to determine if there was a temperature change. The reason why we're determining if their was a chemical reaction is to identify if it is exothermic or endothermic.
