fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation involves evaporating a liquid into a gas phase‚ then condensing the gas back into a liquid and collecting the liquid in a clean receiver. Substances that have a higher

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide‚ a household blender‚ potatoes (3 medium size potatoes‚ that are peeled and quartered)‚ tap water‚ 8 test tubes‚ 8 transfer pipets‚ sugar packets‚ salt‚ a small saucepan‚ a refrigerator with a freezer‚ stove

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Chm235LL 2/18/14 Caffeine Isolation Lab I. Abstract Solid crude caffeine was extracted from tea and purified via sublimation. The melting point was experimentally found at 215.9-218.7oC. II. Introduction Caffeine is the most dangerous substance being used in lab this semester‚ but it’s also one of the most favorite chemicals commonly ingested among college students. The main purpose of this lab was to extract caffeine from a beaker of about 20 ml of tea. Sublimation was an effective and convenient

drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and to test for contaminates such as NaCl and KCl. These tests helps us to determine the properties of the drilling fluid and so what can be done to make the mud perform more efficiently.

1 gram of an impure‚ unknown substance solid. Make sure to stir the mixture before measuring the sample; record the mixture’s code in the data section. 2. Add approx. 25-50 mL of water and several boiling chips to a 125 mL Erlenmeyer flask and heat the water to a gentle boil using a hotplate. 3. On a second hotplate‚ place a 125 mL Erlenmeyer flask containing the one gram of unknown solid along with a boiling chip. 4. Using a ring clamp‚ slowly pour approx. 5-10 mL of boiling water into the flask
