  • Discussion On Redox Titration

    Vitamin C by Redox Titration with Iodine Vitamin C (ascorbic acid) is an antioxidant that is essential for human nutrition. Vitamin C deficiency can lead to a disease called scurvy, which is characterized by abnormalities in the bones and teeth. Many fruits and vegetables contain vitamin C, but cooking destroys the vitamin, so raw citrus fruits and their juices are the main source of ascorbic acid for most people. One way to determine the amount of vitamin C in food is to use a redox titration. The redox...

    Discussion The acid neutralising capacity (ANC) of 3 brands of calcium carbonate (CaCO3) tablets was determined by reacting the tablets in excess standardized hydrochloric acid (HCl) and then back-titrating with a standardized sodium hydroxide (NaOH) solution. Back titration was required for two reasons. Firstly, CaCO3 tablets are poorly water-soluble but dissolve rapidly in acid. Secondly, CaCO3 is a weak base so it is difficult to determine the end point of the reaction if titrated directly. ...

    Lab Write Up: Acid-Base Titration Problem: How can the concentration of acetic acid in vinegar be determined with 0.1M HCL and NaOH solution of unknown concentration? Hypothesis: If the concentration of a base NaOH is found using a known concentration of an acid 0.1M HCL by the process of titration, then the now known concentration of NaOH can be used to titrate acetic acid in vinegar to determine its concentration. This is possible by using the formula Ma*Va = Mb*Vb. Introduction:...

  • Redox potential

     Redox potential – CV Acetonitrile Adjusted sensitivity Each ;line represents diff scan rates all been overlayed on one digarm Scan rates ranged from 0 .1 s-1 to 1 Peak due to iodide oxidation is read from +peak to – peak bottom line. Iodide to triiodide Glycol Didn’t work Using equation ip = 2.69 ×105 n3/2 A D1/2 C ν1/2 compare to linear equation y = mx+c y = peak current x = V1/2 c = zero Therefore m is = everything else C = concentration 0.05 M ethylene glycol (acetonitrile...

  • Redox Reactions

    Redox reactions (Redox terminology, galvanic cells, standard electrode potentials, strength of oxidizing/reducing agents, corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents, such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions...

  • Back titration

    Synopsis The objective of this experiment is to determine the percentage by mass of calcium carbonate,CaCO3 in toothpaste using back titration technique. A known weight portion of toothpaste is obtained to react with known volume and concentration of standard acid solution. After completing the reaction, the resulting solution containing excess acid is back titrated with known volume and concentration of standard base solution. Determination of excess acid after reaction allow us to calculate the...
