Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…

Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

The materials used in this project were general protective personal equipment such as lab coat, gloves and googles, 125 milliliter Erlenmeyer flask, 50 milliliter burette, 50 milliliter beaker, graduated cylinder, scale, vitamin c, phenolphthalein, methyl orange, deionized water and the following chemicals: sodium hydroxide, potassium hydrogen phthalate, hydrochloric acid and sodium bicarbonate. When it comes to these chemicals, make sure to wear the general protective personal equipment and…

Methods: To begin, our group acquired three premade vials of .1ml mammal blood with coagulant. We then labeled the vials numbers one, two, and three. In vial number one we added 1 ml of Stock 300 mM NaCl, and no distilled water. This resulted in a NaCl concentration of 1.8 percent. In the second vial we added .5 ml of Stock 300 mM of NaCl, and .5 ml of distilled water. This resulted in a NaCl concentration of .9 percent. In the third vial we did not add any Stock 300 mM of NaCl, and 1 ml…

Concentration of Acetic Acid in Vinegar Nalebra Barnett, AAHCA, BSHA University of Central Oklahoma General Chemistry II Lab March 28, 2017 Dr. Lane Whitesell Lab 12. Concentration of Acetic Acid in Vinegar. This laboratory is to determine the concentration of acetic acid in vinegar using molarity and percent by mass of acetic acid in vinegar. This means, vinegar is a crucial solution of acetic acid (HC2H302) in water. Molarity (in mole/L), or mass percent expressed the…

Problem Statement: How do different amounts of soil affect the pH of water? Is the relationship the same for different types of soils? Background: PH is a measurement of how many ions of hydrogen are found in a solution. The pH scale measures how alkaline or acidic an object is. The scale has numbers ranging from zero (which are considered the most acidic) to fourteen (the most alkaline, otherwise known as the most basic). Pure water has a pH of seven, however most water, either from the tap or…

A range of concentrations (1nM to 30μM) of acetylcholine (Ach) and 5-hydroxytryptamine (5-HT) was administered to organ bath containing rat ileum. Ach and 5-HT induced contractions from 3nM (Fig. 1) and 10nM (Fig. 2) onwards respectively, both generating a shallow slope at the beginning of the concentration-response curve. EC50 of Ach is 7.47 x 10-7M whereas EC50 of 5-HT is 7.97 x 10-7M. The contraction generated by Ach and 5-HT was expressed in % Emax. As shown in Fig. 1 and 2, % Emax…

prohibited and in clear violation of the Law of War. My second response will be to advice that the operation order be revised before the execution of the order because the destruction of civilian property unnecessary and cannot be justified under military necessity. Question # 2: Would you change it? If so how and why? To minimize damage of ease unnecessary suffering of the people. The operation order should be revised and consider…

Determining Value for Money of Different Brands of Vinegar Aim – To compare the amount of acetic acid found in two different brands of vinegar to see which is the most cost effective. Materials – • Apron • Safety Glasses • Hair Tie (If appropriate) • 50mL burette • 250mL conical flask • 2 x Beaker • Measuring Cylinder • Labels • Pencil • Standard solution of Sodium Hydroxide, NaOH(aq) • Two different brands of vinegar • Phenolphthalein Indicator • A clean white tile • Distilled water • Retort…

Introduction: Acids and bases are often described using the Bronsted-Lowry theory which states that acids are proton donors, while bases are proton acceptors (Thorne, 78). This means that an acid has additional H+ ion(s) that can be given, whereas a base lacks these ions and will accept them. Acids and bases can further classified as strong or weak. A weak acid, such as HF, will not ionize completely, meaning that only some of the H+ ions will be lost. A strong acid will however, will release…
