Using mortal and pestle‚ crush aloe vera and get it’s extract. 3. Pour the aloe vera extract‚ lemon juice and baby oil in pot and simmer using lower heat temperature until it boil. 4. After you simmer/boil the mixture‚ add the banana peel and continue to boil it. 5. Finally‚ if the solution became viscous‚ set it aside and make the insect repellant. Procedure #2: (for mosquito repellant) 1. First‚ clean the taheebo leaves and put under the sun to dry for 30 minutes to 1 hour. 2. After the leaves

PRINCIPLES OF CHEMISTRY LAB I Experiment 2 Separation Of Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixture may be a solid‚ liquid‚ gas‚ or some combination of those states. Mixtures can be found almost every wher in our everyday lifes and some common examples are * sand and water * salt and water

Purpose: The purpose of this separations lab was to see what the most efficient way is to separate a dry mixture using all kinds of materials. The mixture was of salt‚ sand‚ iron filings‚ and bird seed. Results: The results of mass recovered were very different from what the actual mass was. The iron filings were about the same besides recovering 0.1 extra gram. For the bird seed‚ there was 0.7 grams more collected from the original mass that is 2.0 grams. The sand had 2.5 grams recovered‚ where

As you are boiling the water for the Jell-O‚ take a tablespoon of the thick‚ pulpy pineapple mixture and pour it into one of the three small bowls. Save that tablespoon for use with that bowl only. Mark the bowl as “room-temperature pineapple juice.” 4. Take the rest of the thick‚ pulpy mixture and pour it into a pot. You will

Theory: Distillation is the conversion of a mixture of substance into vapors which is afterwards condensed to the liquid form. It cans separation or purification of substances by taking advantage of differences in volatility. The purpose of this lab is comparing the efficiency of two distillation methods with the mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation‚ you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf‚ which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment.

Add a consistent amount of each chemical. Try to count the grains of copper sulfate so that you are adding close to the same amount to each reaction. As an option‚ premix the dry ingredients in a clean‚ dry container. Add enough luminol‚ perborate‚

DISTILLATION- SEPARATION OF A MIXTURE Ronald Ogbu‚ Alex 27th Aug. 2013 Purpose: To separate mixture of acetone and toluene using simple‚ packed and unpacked distillation columns. Results and Discussion: There were three distillation setups: simple‚ unpacked and pack fractional. All three procedures had different distillation apparatus but the unknown mixture was the same for all. The unknown liquid in a 50 ml round bottom flask was heated in a heating mantle such that a
