    Besides, the neutralization balance equation for the titration of oxalic acid (C2H2O4) with sodium hydroxide (NaOH) is as below. C2H2O4 (aq) + 2NaOH (aq) Na2C2O4 (aq) + 2H2O (l) From the equation, it clearly showed that the 1 mole of oxalic acid (C2H2O4) will react with 2 mole of sodium hydroxide (NaOH) to produce 1 mole of oxalic acid sodium salt (Na2C2O4) and 2 moles of water (H2O). The mole ratio of oxalic acid and sodium hydroxide is 1:2 Thus, to calculate the actual concentration

    The aim of this lab is to determine the concentration of a potassium hydrogen phthalate solution (HKC8O4H4) using acid‐base titration. Introduction: Titration is a technique that chemists use to determine the unknown concentration of a known solution (we know what chemical is dissolved, but not how much in a solution). Because we know what the chemical is, we know how it will react with other chemicals and we can use that reaction to determine the concentration of the solution by measuring the formation

  • Hydrochloric Acid Base Titration

    731 Words  | 3 Pages

    Introduction A titration is an analytical method in which the unknown concentration of a solution, analyte, is calculated by determining the volume of a solution with known concentration needed, titrant, to completely react with the analyte. In this case the hydrochloric acid solution (HCl) is the analyte since its concentration is unknown and it is titrated with sodium hydroxide (NaOH) which serves as a titrant since its concentration is known. This is as an acid-base titration and in it the hydrogen

  • Redox Titration Reaction

    1207 Words  | 5 Pages

    INTRODUCTION Iodometry is a common example of redox titration reaction, involving a series of steps used to quantitatively determine the amount of oxidising agent required. The reaction mainly oxidises iodide (I-) to iodine (I2) and is a reversible process. Oxidising agent such as Copper (II) Sulfate (CuSO4) is added to react with Potassium Iodide (KI) to yield I2. Excess KI is required to get triiodide ion (I3-), which is very water-soluble, compared to I2, which is sparingly water-soluble. This

    Introduction: The acid-base titration experiment is the use of a titrant, an analyte, and an indicator. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.1 The titrate is what is later released into a beaker or flask that is filled with the analyte and indicator. The color change happens because of the indicator

  • Equivalence Point In An Acid-Base Titration

    845 Words  | 4 Pages

    End point in this acid-base titration experiment refers to the point where the chemical reaction has reached its conclusion and no additional titrant should be added. The end point of this experiment can be obtained when the indicator used changes colour. For example colourless to light pink when phenolphthalein is used and red to orange and subsequently yellow when methyl orange is used. Equivalence point, also known as stoichiometric point in an acid-base titration refers to the point where the
