the analysis, the content of the analyte can be calculated. There are several assay reactions which are used in potentiometric titration: • Acid/base aqueous • Acid/base non-aqueous • Redox • Precipitation (e.g. Argentometric titration) • Complexometric

Lecture 10 - Redox Titrations

Redox Titrations -the oxidation/reduction reaction between analyte and titrant -titrants are commonly oxidizing agents, although reducing titrants can be used -the equivalence point is based upon: A ox + B red! A red + B ox Rx’n goes to completion after each addition of titrant – Potentiometric Titration: Titration reaction: Ce4+ + Fe2 ...

Wet Etching - University of Washington

6 + HNO 2 + H 2 O + H 2 – Etching occurs via a redox reaction followed by dissolution of the oxide by an acid (HF) that acts as a complexing agent. – Points on the Si surface randomly become oxidation or reduction sites. These act like localized electrochemical cells, sustaining corrosion currents of ~100 A/cm2 (relatively large).

Lab #6 Chemical Transformations of Copper

6. In Part E of the experiment, the zinc metal is added to undergo a redox reaction with the copper(II): Zn + Cu+2 ! Cu + Zn+2 Hydrogen gas is also generated in this step. How is the hydrogen gas formed? 7. Why is a large excess of zinc added in the reaction of Part E?

(aq) + 6 H+(aq) → 2 Mn2+(aq) + 5 O 2 (g) + 8 H 2 O(l) Cette réaction nécessite des protons H+(aq). Elle se déroule donc en milieu acide. Tous les couples oxydant / réducteur ne peuvent ependant pas exister dans un tel milieu… Certains ouples n’évoluent, en effet, qu’en milieu asique. Exemple de réaction se déroulant en milieu ...
