Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils. It did great job at pulling stains right out of the cloth. This products

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

Figure 2 Figure 3 Figure 1 show the crystallisation reaction when the saturated sodium chloride solution was added to the cool reaction mixture. The salt of p-Toluenesulphonic acid started forming. Figure 2 show the wet crystal after the precipitated salt was being filtered by suction. The wet crystal was light purple in colour. Figure 3 show the end product after drying the wet crystal at 105°C in the drying cabinet (oven)

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Acid-Base Balance and Fluids and Electrolytes Student’s Name Institutional Affiliation Date Due Respiratory Acidosis Respiratory acidosis refers to a medical defect in which hypoventilation occurs leading to increased concentration of carbon dioxide in the blood and decreased level of pH. Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

Abandoned Acid Mine Drainage at Shoup’s Run Introduction Acid mine drainage (AMD) is an industrial waste which is the result of the extraction process of the mineral coal from the ground. It causes widespread pollution in the streams above and below the coals fields. AMD is caused when water flows through sulfur-bearing materials forming acidic solutions. It is formed when pyrite (FeS2)‚ an iron sulfide‚ is exposed and then reacts with air (O2) and water (H2O) to form sulfuric acid. 2FeS2 (s)

Thermochemistry (((CLASS INFORMATION)) INTRODUCTION Thermal chemistry was intended to display that chemical reaction and phase changes involve energy. The energy of heat was presented when a change in temperature difference was evaluated. Chemical reactions in a calorimeter were used to determine the amount of heat produced by a reaction. Reactions that absorb heat were noted as endothermic‚ and reactions that release heat were noted as exothermic

The purpose of this experiment was to study the effect acid rain has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions‚ while do slow growth of a seed‚ they do not kill the seed. A seed can be dormant for a majority of its lifespan‚ seeds watered with acid solutions stayed in a dormant condition. For example‚ trial three
