Electrochemistry Lab Report

electrode (a strip of metal, M) within a solution containing Mn+ ions in which M is any arbitrary metal. The two half cells are linked together by a wire running from one electrode to the other. A salt bridge also connects to the half cells. Through electrochemistry, these reactions are reacting upon metal surfaces, or electrodes. An oxidation-reduction equilibrium is established between the metal and the substances in solution. When electrodes are immersed in a solution containing ions of the same metal...

Electrochemistry

Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (a metal or a semiconductor) and an ionic conductor (the electrolyte), and which involve electron transfer between the electrode and the electrolyte or species in solution. If a chemical reaction is driven by an external applied voltage, as in electrolysis, or if a voltage is created by a chemical reaction as in a battery, it is an electrochemical reaction...

Electrochemistry Pre-Lab Questions

Pre – Lab Questions 1. A decomposition reaction may be defined as any reaction in which one reactant, a compound, breaks down to give two or more products. Write the balanced chemical equation for the decomposition of water to its elements. 2H2O(l) 2H2(g) + O2(g) 2. (a) Assign oxidation states to the hydrogen and oxygen atoms in each substance in the above chemical equation. The oxidation state of H2(g) and O2(g) is zero, because they are in their normal state. (b) Based...

Electrolysis Research Paper

on chemical reaction that take place in a solution at the interface of an ionic conductor and electron conductor, and where electron transfer is involved, is called Electrochemistry (Grimshaw, 2000). In electrolysis, where a chemical reaction is conducted by an external voltage, it is called an electrochemical reaction. Electrochemistry focuses on situations that involve oxidation and reduction reactions that are separated but connected by an external electric circuit. The decomposition of water into...
