  • Titration In Gastric Acid Essay

    of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity. In this experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the…

  • Back Titration Of Calcium Carbonate In Toothpaste

    calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed at the end point. This experiment is a success as two results obtained from the experiment were relatively close furthermore, an average of 21.50% of calcium carbonate obtained is close to the literature value of 20%. 2. Introduction There are several…

  • Double Replacement Reactions Lab Report

    Lowry independently expanded the Arrhenius acid definition into one of his own. The Bronsted-Lowry acid is a molecule or ion that is a proton donor. Lewis's definition emphasizes the role of electron pairs in acid-base reactions. A Lewis acid is an atom, ion or molecule that accepts an electron pair to form a covalent that accepts an electron pair to form a covalent bond. Each theory agrees that an acid is a substance that is dissolved in water and is separated. Although…

  • Acid Base Titration Report

    ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

  • Inquiry Based Learning Process Essay

    either acid or base. Note: This activity may take more than one lessons. On the first lesson, students group, discuss and prepare their experiment. On the second lesson, students will have opportunities to carry out the investigation, then record, process, and evaluate their data. Preparing materials In the original experiment, hydrochloric acid and sodium hydroxide solutions have been used as acidic and basic solution, respectively. However, year 9 students might know that hydrochloric acid…

  • Inorganic Chemistry Experiment 3: The Identification Of Unknown

    the other three liquids. It was expected that whichever combination of liquid and black solid formed a blue solution would be H2SO4 and CuO hence, CuSO4 in solution. On identification of sulphuric acid, the following tests were performed expecting the evolution of carbon dioxide on reaction of the acid with carbonates. Therefore, among the soluble solids, (10) exhibited effervescence and was suspected to be sodium carbonate due to its solubility. The powders and crystals were divided…

  • The Volumetric Analysis Experiment

    Also, we used acidic indicator phenolphthalein to determine the end point of experiment when the color turns from colorless into red or pink. Potassium acid phthalate is our primary standard and this huge molecule has molecular mass equal to 204.2 g/mol. (KHC_8 H_4 O_4 ) and it has abbreviation as KHP. Also KHP is monoprotic and will react in a simple one to one ratio: NaOH(aq) + KHC_8 H_4 O_4 (aq) →KNaC_8…

  • Kidney Stones Lab Report

    Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…

  • Equivalence Point Lab Report

    constant variable is the acid which is in the flask. When the solid acid dissolves to form ions, 1 mole of H+ ions are produced for every mole of acid being used. Molarity is used to calculate moles per liter of solution. The most dangerous part of this lab is the risk of getting…
