By following the above procedure, it was determined that my hypothesis was accepted. Initially, I predicted that sugar will have the best solution for making crystals because the sugar dissolves better in water and will be able to make the best crystals in size and shape. During the experiment, I investigated which solution made the best crystals. However, there was some inconsistencies and consistencies. The inconsistencies and consistencies were finding the perfect spot to put the solutions,the

Isaiah McConaga Janay Winston Mrs. Chan Honors Chemistry Background Research The topic is Chemistry of Making Ice-Cream: Lowering the Freezing Point of Water. In this experiment the scientist will be researching how to lower the freezing point of water using salt and/or sugar. The Independent Variable in this experiment is the solutes that the scientist uses which are, chemicals that dissolve in liquids. The Dependent Variable is the temperature/freezing points of the substances(°C). A constant

Periodic Acid Schiff’s - Glycogen PURPOSE: Glycogen is stored mainly in the liver and within the skeletal muscles of the human body. A small amount of glycogen can also be found in the glial cells in the brain. The PAS stain is used to identify basement membranes, fungi, glycogen, some mucins, and mucopolysaccharides. It is a routinely used stain in brain, cornea, liver, and skeletal muscle specimens. PRINCIPLE: One of the most common applications for Schiff’s Reagent is in the Periodic Acid Schiff’s

• The retardation factor or Rf value is the ratio of the distance the compound travels to the distance the solvent travels. The Rf value allows the experimenters to determine if the compound is polar or nonpolar. If the compound is nonpolar (the Rf value is close to 1), then it will have a little to no affinity in the stationary phase. If the compound is polar (the Rf value is close to 0), then the compound is very polar and has little to no affinity in the mobile phase. These determinants will

In order to extract DNA from any living thing, we needed to first gather the materials. Then we began the experiment. Step 1, put in a blender 1/2 cup of split peas (100ml), 1/8 teaspoon table salt (less than 1ml), and 1 cup cold water (200ml). Next, we blended the materials on high for 15 seconds. This allowed the pea cells to separate from each other, so we now had a really thin pea-cell soup. Step 2, poured our thin pea-cell soup through a strainer into another container. Added 2 tablespoons of

(8 points) Score 1. List the values for T-alkalinity for Sample A and Sample B. List the ppm value for sodium carbonate for Sample A and Sample B. Answer: I am unable to answer this question because I don’t think I have enough information. This is asking for exact values and I don’t have the data to answer it

One of the best things to do on a sweltering summer day is to take a nice, cool swim. However, you may have found that the water in your pool occasionally becomes murky and uninviting. When that happens, The Pool Guys in Troy, MO are here to help. With 30 years of experience in the industry and the honor of being the only company in the area to offer full pool service, you can trust their expertise. Whether you have an above-ground or inground pool, cloudy water is caused by three things: Causes

On Thursday August 27, 2015 my group comprised of Elizabeth Cruz, Samantha St. Martin and I initiated experiment. This was constructed of three Alka-Seltzer tablets and three beakers containing different liquids: water, salt water, and vinegar. The drive behind our experiment was to see what factors would make the Alka-Seltzer tablets dissolve faster. My group’s hypothesis was that the strong chemical compounds in vinegar will cause the Alka-Seltzer to dissolve faster and therefore take the shortest

things constant. A good way of sustaining pH homeostasis is through a short term mechanism called chemical buffer system, which are bicarbonate, phosphate, and protein buffer systems. Buffer systems solution resists changes to its pH when a strong acid or base is added. Another system that manages severe changes of pH is the
