To begin this test‚ 3 water baths were set up. One bath was cooled to 0 degrees celsius‚ one was heated to 37 degrees celsius‚ and one was boiled to 100 degrees celsius. 1 of the four test tubes containing 2 ml of 100 units/ml catalase was put in to each of the three water baths‚ one at a time. While the tubes sat in the baths‚ the 4 H2O2 vials were prepared and the depth of the H2O2 was recorded. After the 0 degree celsius test tube incubated in it’s bath‚ it was taken

Purpose The purpose of this laboratory is three fold: 1. Familiarize the student with the concept and meaning of pH 2. Provide the student experience in measuring pH a. pH testing paper 3. Test the student’s hypothesis as it related to the pH of common solutions Hypothesis The pH of the tested solutions will be in the order of the following according to a pH scale: 1. Lime juice 2. Orange juice 3. Soda 4. Iced Tea 5. Milk 6. Water 7. Soapy water Material Required To facilitate

Red Bull and Sugar Free Red Bull NMR Post Lab Report Abstract Viewed as one of the most significant tools in analytical chemistry‚ the Nuclear Magnetic Resonance (NMR) is a spectroscopy tool often used by chemists to determine the molecular profile – quality and quantity of the major components - of any given organic substance. Operating on basis of spectroscopy (study of the interaction between matter and radiated energy - Harris)‚ the NMR can be either a one (1H NMR) or two (1H/13C NMR) dimensional

when baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose‚Lactose‚Sucrose‚and Starch.The main thing that make some of these carbohydrates different from each other is if it’s a Monosaccharide‚ Disaccharide‚or Polysaccharide. Monosaccharide

exists in our small intestine and our small intestine uses acid to break down food. The result from the lab prove my hypothesis correct because lactase worked well at body temperature and it also worked well at pH of 4.5 to 5.5 mg/dl proving that lactase works best at an acidic pH number. The lab shows that the highest amount of glucose is made by temperatures close to body temperature. In our our lab‚ we found that at 35 °C 500 mg/dl glucose was produced‚ which was the highest number of glucose that

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion
