    • 11 Pages

    Weak Acid Titration Abstract: Our method for determining the unknown weak acid was to determine the equilibrium constant K from the molecular weight of the weak acid from our titration data. In this lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our

    Unit 10 Assignment 2: The Endocrine System: Diseases and Age-Related Changes Human Chorionic Gonadotropin (hCG) Human chorionic gonadotropin is a hormone that can be detected in the urine or blood of both males and females. It is more often seen in pregnant women but can also be found in cancerous tumors of the uterus and testicles. HCG aides in establishing pregnancy and has also been used here lately in some forms of weight loss programs although not always approved. Cushing’s Disease Cushing

    AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with

    BASE ISOLATED BUILDINGS What is base isolation? When a building is built away (isolated) from the ground‚ resting on flexible bearings or pads known as base isolators. It is of the most popular means of protecting a structure against earthquake forces. HISTORY The first evidence of architects using the principle of base isolation for earthquake protection was discovered in Pasargadae. One of the world’s first base-isolated structures – the William Clayton building Base Isolation

    Standard Solution (Part A and B) ABSTRACT The purpose of this experiment is to prepare a standard solution of potassium hydrogen phthalate and use titration to perform an acid/base reaction between the potassium hydrogen phthalate and sodium hydroxide to standardize approximately 0.10 M sodium hydroxide solution. To prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution

    Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

    The Answer by Karl Nemsow Voyager1 sails through deep space all alone. It has been on its journey since 1977 sending back glimpses of the solar system to help humankind find some answers. One of the greatest questions asked by humankind is what‚ or who‚ else might exist out in our grandiose cosmos. A cosmos 13.7 billion years old‚ which is so massive that it is incomprehensible to the human mind. Dr Vince Hawking tried to comprehend such concepts every single day. It made him wonder if
