PDF 1. ELECTROCHEMISTRY
In galvanic cells the reactions are spontaneous, caused by the different reduction potentials of the ions in the different half-cells. In electrolytic cells, as you will see in the next experiment, the reactions require the work supplied by an external voltage. In this experiment, you will make several galvanic cells and measure the voltage ...

Electrochemistry: Galvanic Cells and the Nernst Equation
Electrochemistry: Galvanic Cells and the Nernst Equation Introduction. In this experiment the goal is to investigate how to generate an electric current from a spontaneous redox chemical reaction. The device in which chemical energy is changed to electrical energy is called a galvanic cell. Batteries are an everyday example of galvanic cells.
Experiment 9 Electrochemistry I - Galvanic Cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction, two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction).

PDF Experiment 18: Galvanic Cells and Corrosion
Iron undergoes a two-step oxidation process as follows: step 1: Fe (s) → Fe2+ + 2 e- step 2: Fe2+ → Fe3+ + e- The final oxidation product, iron (III), then combines with oxygen and water to form iron(III) oxide, or what we call "rust". In today's experiment you will determine which metals enhance the corrosion of iron and which inhibit the ...

Making and Testing a Simple Galvanic Cell.
A Galvanic cell is an electrochemical cell that uses a spontaneous chemical reaction to produce electrical energy. Also known as a voltaic cell. A galvanic cell is usually made of an electrolyte and two electrodes made of two different metals (with two different reactivity rates). The primary difference between metals is the ease with which ...
