    William Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can

    Experiment TITRATION OF A COLA PRODUCT The CCLI Initiative Computers in Chemistry Laboratory Instruction LEARNING OBJECTIVES The objective of this laboratory experiment is to determine the molar concentration of phosphoric acid in a cola product. BACKGROUND Titration is an analytical technique used to find the concentration of a known volume of unknown substance by adding a known concentration of a known substance. As the unknown and known substance react‚ we look for a "telltale" indication

    CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION Calcium is the largest mineral in the human body‚ where it plays an important role in absorption and the releasing of calcium in the body is through the intestinal and kidney. The calcium in the body is controlled by hormones and vitamins (Takano et al). The three major components that involve in the controller the calcium is parathyroid hormone (PTH)‚ calcitonin and Vitamin D. The consistent the calcium in the body from despite variation in-take and excretion

    Introduction A titration is a technique used to find the solution of known concentration in the concentration of another unknown solution. Typically‚ the known solution is added from a known quantity of unknown solution until the reaction is complete. Titrations are also often used to determine the pH of a solution. This is important because without knowing how acid or basic a solution is people could hurt themselves and others but mixing chemicals together that are lethal. The objective of the

    amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head and bones are removed as opposed to using whole anchovies found at hawker stall. The source of calcium present

    first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO‚ which is mercuric oxide. However‚ Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808‚ calcium metal was not available in large amounts until the beginning of the twentieth century. Before
