This knowledge will enable a strategy to be developed by which chemical reactions may be used to generate electricity. The course will demonstrate how electrochemical measurements may be employed to construct a scale of the oxidising and reducing power of chemical species. The course is supported by practical classes. Learning outcomes By the end of the course, a successful student should be able to: 1. Balance chemical equations for chemical reactions. 2. Estimate the reaction free energy from a cell emf and predict the spontaneous direction of a redox reaction.

Identity of electricities; first researches on electro-chemistry. Identity of electricities; first researches on electro-chemistry. in favour of the 'Identity of Electricities.' His paper upon this subject was read before the Royal Society on January 10 and 17, 1833. After he had proved to his own satisfaction the identity of electricities, he tried to compare them quantitatively together. The terms quantity and intensity, which Faraday constantly used, need a word of explanation here. He might charge a single Leyden jar by twenty turns of his machine, or he might charge a battery of ten jars by the same number of turns. The quantity in both cases would be sensibly the same, but the intensity In his subsequent researches 'On the absolute Quantity of Electricity associated with the Particles or Atoms of matter,' he endeavours to give an idea of the amount of electrical force involved in the decomposition of a single grain of water. He is almost afraid to mention it, for he estimates it at 800,000 discharges of his large Leyden battery. This, if concentrated in a single discharge, would be equal to a very great flash of lightning; while the chemical action of a single grain of water on four grains of zinc would yield electricity equal in quantity to a powerful thunderstorm. Thus his mind rises from the minute to the vast, expanding involuntarily from the smallest laboratory fact till it embraces the largest and grandest natural phenomena. In reality, however, he is at this time only clearing his way, and he continues laboriously to clear it for some time afterwards. He is digging the shaft, guided by that instinct towards the mineral lode which was to him a rod of divination. '

Tutorial #11 Electrochemistry e.g. What is the reduction potential for the hydrogen electrode in a solution having a pH of 4.00? The half reaction is 2 H (aq) + 2 e H 2(g, 1 atm) If pH = 4.00, then [H M. For this reaction, Q = p / [H Thus, E = E o - RT/nF ln(Q) = 0.00 V - 8.314(298)/(2)(96500) ln(10 = -0.24 V The lesson to learn here is that the Nernst equation applies to half reactions as well as to complete REDOX reactions! Electrolytic Cells These cells have E cell e.g. for the reaction using the two half-reactions: Fe + 2 e Fe E = -0.440 V 2 Ag 2 Ag + 2 e E = -0.800 V overall: Fe + 2 Ag Fe + 2 Ag E cell = -1.240 V To make this reaction occur, we must apply a potential of at least -1.240 V. The potential must be applied so that electrons are being supplied to the electrode where reduction is occuring. This is always the cathode, and in this case it is the iron electrode. Predicting the reactions at the electrodes In an eletrolytic cell, there is usually more than one species that could be oxidized at the anode, and more than one species that could be reduced at the cathode. Not only are hte obvious species present (e.g. metals and metal ions), but there is also a solvent (usually water) and some other ions, many of which are oxidizable or reducible. You need a rule to predict what happens at each electrode - perhaps the metal ion you are trying to reduce will not get reduced! The rule is: the reaction with the more positive half-reaction potential will occur preferentially For example , suppose you were to electrolyze

30. 10502. Electro-chemistry Of Stainless Steel Can someone help us with the electrochemistry of this phenomenon ? George C. Malachowski Cytomation Inc. - Fort Collins, CO, USA. http://www.finishing.com/105/02.shtml

Letter # Electro-chemistry of Stainless Steel Aug 27, 2001 We build small saline filled chambers for biological purposes. It is required to supply a voltage to a stainless steel electrode which is placed in direct contact with the saline. The saline consists of 150 millimoles NaCl and 16 milimoles of Na2HPO4 (Sodium dibasic Phosphate) which acts as a buffer. If a stainless steel electrode and a copper electrode are placed in this solution and a voltage of about 3.5 volts is applied, the cathode (copper) discharges gas, which we assume to be hydrogen. The anode begins to form a light green soluble substance which fits the description of ferrous chloride. However if we instead use 16 millimoles of NaH2PO4 (monobasic)we see a colorless gas (oxygen ?)at the anode and no green substance at all. Can someone help us with the electro-chemistry of this phenomenon ? George C. Malachowski Cytomation Inc. - Fort Collins, CO, USA. Aug 29, 2001 At the anode you are generating Oxygen and Chlorine and Hydrogen at the cathode. The metals in the Stainless Steel are forming Chloride salts. Nickel Chloride, Ferrous Chloride and Chromic Chloride. If the pH is above 8.0, the Nickel will probably precipitate. In time, you may find deposited Iron on the cathode with traces of Chrome. The deposit will be smutty brown with possibly a slight green tint. If you continue electrolysis, the SS will dissolve completely. The Di Sodium Phosphate used alone should be OK. If you require the Sodium Chloride for some reason, I recommend you use either a Platinum metal anode, or a Platinum clad or Platinum plated Titanium material. Carbon can also be used but will eventually fall apart. Iridium Oxide is the best of all but may be cost prohibitive.

31. SHAC Meeting Report a model to teach him what he should avoid Faraday and Davy s electrochemistry . Faraday s knowledge of electro-chemistry derived from Davy - very early http://www.open.ac.uk/ambix/reports/march2001.htm

Meeting report Report of Meeting: "History of Electro-chemistry" - a meeting to mark the bicentenary of Humphry Davy's taking up the Professorship of Chemistry at the Royal Institution. 23 March 2001, The Royal Institution The meeting was organised jointly by the Royal Institution, the Historical Group of the Royal Society of Chemistry, and the Society for the History of Alchemy and Chemistry. Speakers were Professor David Knight, Dr Frank James, and Dr Mary Archer. David Knight called his paper, "New understanding, new elements: Davy's electrochemistry". Gravity is universal; but chemical affinity is elective - some substances react together and others don't. In 1800, chemistry had recently acquired a new vocabulary and a theory of burning from Antoine Lavoisier but awaited its Newton, who would explain affinity simply, in terms of forces. Then Alessandro Volta announced that when two different metals are separated by wet cardboard, an electric current flows. Davy (1778-1829), a young Cornishman working in Bristol, believed that this could not be due to mere contact - a chemical reaction must be generating electricity. Appointed, in 1801 to the Royal Institution in London, Davy attracted audiences that maintained his research laboratory. Frank James' The early 1830s was a very creative period for Faraday.

Nanowetenschappen Contact Sitemap Search Printable version Solid state electro-chemistry Several solid inorganic oxide systems show appreciable conductivity for oxygen ions. An important application of this property is found in the so-called Solid Oxide Fuel Cells (SOFCs). These SOFCs can transform chemical energy directly into electrical energy with high efficiency and without pollution. The basic SOFC consists of three different layers of inorganic materials: Two electrodes, which may consist of composite materials, separated by a ceramic electrolyte. At one electrode, the cathode, atmospheric oxygen (O ) is transformed into oxygen ions (O x system. The electrodes used in the investigations will be made of porous platinum or gold to study extremes in the effect of oxygen dissociation activities. The exchange between gaseous oxygen and lattice oxygen of the bulk oxides is an important step in the total transport of oxygen. Oxygen isotope ( O) exchange is used in the study of these surface exchange processes. Electrochemical impedance spectroscopy (EIS) has proven to be an important research tool in the investigations mentioned, hence also special attention is paid to a further development of this technique.
