I held the chemicals at approximately a 90 degree angle for consistency Introduction: Redox reactions occur when both oxidation and reduction take place. All atoms can be assigned an oxidation number‚ which is a positive or negative number that help in determining the reducing and/or oxidizing agents in an equation. An increase in the oxidation number of an atom from

Name: Date of experiment: 04/02/12 Date of report: 04/03/12 Title: Oxidation – Reduction Activity Series Purpose: To determine relative oxidizing and reducing strengths of a series of metals and ions. Oxidation and reduction reaction occur simultaneously side by side. A reduction reaction occurs only if an oxidation reaction occurs and vise-versa. Electrons are given in oxidation while in reduction electrons are gained. Oxidizing agent is a chemical substance which has a large tendency to

Formation of an Alkene by Alcohol Dehydration Lab Report Balanced Chemical Equation for the Main Reaction Mechanism The acid-catalyzed dehydration of secondary and tertiary alcohols involves non-isolable carbocation intermediaries. In the first step of the of the reaction mechanism below‚ a phosphoric acid catalyst adds a proton to the oxygen atom of the alcohol to form an oxonium ion. The OH is converted to a better leaving group as the positive charge on the oxygen weakens the carbon-oxygen

of that substance by titrating the sample with a solution of a strong oxidizing agent. In this lab‚ a solution of KMnO4‚ an oxidizing agent‚ will be standardized by titration with a solution containing a known concentration of iron (II) ions‚ (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution

Oxidation of Cyclohexanol Introduction: The oxidation of cyclohexanol involves using household bleach to oxidize this secondary alcohol and produce a ketone product‚ cyclohexanone. Oxidation-reduction (redox) reactions occur when the oxidation state of atoms change due to a transfer of electrons. Oxidation occurs when electrons are ‘lost’ to the formation of bonds and reduction occurs when electrons are ‘gained’ in the braking of bonds (Levine). Using this reaction and its product‚ a redox experiment

1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion
