To what extent does varying the Sodium Chloride concentration impact the mass change of Solanum tuberosum cubes? Katie Hynek 12/11/15 Personal Engagement: Every Thanksgiving my aunt and grandma switch off making mashed potatoes and every year they use the same recipe. This year it was my aunt’s turn and when we went to eat the mashed potatoes they were super salty. After thanksgiving dinner that year I became interested in figuring out how the using the same recipes the outcome could be so different

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

STANDARDIZATION OF HERBAL MEDICINES/PRODUCTS: PREAMBLE: Herbal medicine is the most primitive traditional approach to the treatment of diseases and ailments. It is called herbal medicine because it involves the use of plants or plant parts. There is no doubt that herbal medicines provided the first basis for therapeutics before the development or advent of orthodox medicine. Despite the fact that‚ over the years‚ chemists have synthesized a large number of chemical substances‚ many of which have

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Chemistry 1211K Lab Report Briana Limage Drawer #D20 Tuesday December 2‚ 2014 Lab Day and Time: Tuesday 2-5 Unknown # 4224034-DF14 Introduction The purpose of this semester long experiment was to determine an unknown organic acid. An organic acid is an organic compound with acidic properties. A base reacts with acids to form salts. Titrations are used to determine the concentration of unknown substances. The purpose of the KHP experiment was to determine the molarity of NaOH. HCl

tubes • Mortar and Pestle • Refrigerator • Hydrogen Peroxide • 7.0 pH Phosphate buffer solution • Thermometer Methods The potato was crushed with a mortar and pestle to make a slurry (the catalase) and poured it into a 250 ml beaker. Four 100 mm test tubes (marked at every cm) were filled from the beaker with a mixture of the catalase and a 7.0 pH phosphate buffer solution to the 1 cm mark

Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which
