Digging Deeper: What to Expect From These Resources

  • Introduction: * A clear definition of diazonium titration and its purpose. * The *chemical reaction* involved in diazotization (the reaction between a primary aromatic amine and nitrous acid to form a diazonium salt). * The importance of *maintaining a low temperature* during the titration to prevent decomposition of the diazonium salt. * A description of *the role of sodium nitrite (NaNO2)* as the titrant.
  • Potentiometric (Electrometric) Method for Endpoint Determination: Expect detailed coverage of: * The *principle of potentiometry* and how it is used to detect the endpoint in a diazotization titration. * The use of an *electrochemical cell* consisting of an indicator electrode (e.g., platinum electrode) and a reference electrode (e.g., calomel electrode). * How the *potential difference between the electrodes changes* as the titrant is added and how this change is used to determine the endpoint. * How to create a titration curve.
  • Types of Diazotization Titrations: Expect in-depth explanations of each type:
    • Direct Titrations: * The *direct titration of the aromatic amine with sodium nitrite*. * What indicators are used for this and why. * What the reagent is. * *Suitable for relatively strong amines*. * Examples of compound tested
    • Reverse Method: * The *addition of an excess of sodium nitrite* to the aromatic amine, followed by *back-titration of the excess nitrite* with a standard solution of a reducing agent (e.g., potassium iodide). * Used when the *direct titration is slow or the endpoint is difficult to detect*. * Examples of what it tests for.
    • Special Methods: Expect descriptions of specialized techniques like: * *The use of specific catalysts* to accelerate the diazotization reaction. * *Variations for compounds that do not react readily or have interfering groups.* * Examples and explanation of the processes
