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

the pineapple into a thick‚ pulpy mixture of fresh pineapple. You need about a cup of this mixture. 2. Prepare the Jell-O as described in the directions on the box. 3. 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

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.

Set out the two clear plastic cups that came with the "Cool Blue Light Experiment Kit" (item # 3053439) from Edmund Scientific at scientificsonline.com Add one scoop each of luminol and perborate mixtures and a few copper sulfate crystals to each cup. 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

Until‚ a boy gets a face painting that’s generally associated with a girl. Maybe there’s a reason for it like: an older sibling of the opposite sex had one or he’s forever fascinated with the subject and that’s his way of expressing it. On the other hand‚ it is okay for a little girl to have a masculine

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken‚ and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next‚ find the mass of the 250mL beaker‚ zero out the scale

evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures‚ it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture‚ another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials
