Electrochemistry INTRODUCTION Part I An electrolytic cell uses electricity to bring about a chemical reaction whereas a voltaic cell uses a chemical reaction to produce electricity. The electrolytic cell used in today's experiment involves the following reaction: M( s 2 H (aq) M aq H g where M represents an unknown metal. As you can see, it is an oxidation -reduction reaction. By measuring the temperature, pressure and volume of hydrogen, and using the Ideal Gas Law equation, PV = nRT, you will be able to determine the number of moles of hydrogen gas formed. From the balanced equation for the reaction and the mass of the metal that has reacted, you can then calculate the number of moles of metal that has reacted and the atomic weight of the metal. Also, it would be interesting to see how the moles of hydrogen produced compares with the moles predicted based on the following relationships: coulombs amperes x seconds one mole of electrons 96,500 coulombs A coulomb represents the amount of electricity carried in one second by a current of one ampere.

Electrochemical Education The purpose of this Web site is to collect in one location resources useful to educators attempting to incorporate modern electrochemical techniques into the undergraduate chemistry curriculum. The availability of low-cost, high performance potentiostats has put the capability of using sophisticated electrochemical techniques within the the reach of many undergraduate chemistry programs. However, unlike spectroscopic and chromatographic techniques, voltammetric techniques have not been widely adopted in most chemistry curricula. The National Academy of Science's publication, New Horizons in Electrochemical Science and Technology , states that "topics such as electrolytes and galvanic cells have been relegated to cursory treatment in freshman chemistry", "there has been a gradual disappearance of electrochemical coverage in most physical chemistry courses", and thus "most undergraduate students are ill prepared in ...electrochemistry". The goal of this Web site is to facilitate use of modern electrochemical techniques in undergraduate curricula by collecting experiments and information which may be useful to faculty attempting to use these tools with students. In particular, it is hoped that non-electrochemists will find materials here which will enable them to add voltammetric techniques to student laboratories. Why electrochemistry?

Building a plastic hydrogen bomb. Electromachining, electroetching, and electroplating. Building your own solar battery. A flat panel solar battery. Make a solar cell in your kitchen A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. If we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour. Our solar cell is made from cuprous oxide instead of silicon. Cuprous oxide is one of the first materials known to display the photoelectric effect , in which light causes electricity to flow in a material. Thinking about how to explain the photoelectric effect is what led Albert Einstein to the Nobel prize for physics, and to the theory of relativity. Materials you will need The solar cell is made from these materials: A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.

What is electrochemistry? As its name suggests, electrochemistry is the science that unites electricity and chemistry. By using electrochemical principles, chemists and engineers design ways of converting electrical energy into the chemical energy of desirable materials: aluminum, nylon and bleach are everyday commodities that are produced by such an electrochemical synthesis . Conversely, chemical energy may be converted into electrical energy: batteries and fuel cells are devices for performing this conversion in a way that is beneficial for mankind. Nature can convert chemicals into electricity in ways that we regret: corrosion is an example of this unwelcome conversion. Electrochemistry has many uses other than electrosynthesis, energy creation, and corrosion inhibition. Electrochemical analysis is one of the most direct and accurate ways of measuring such things as the purity of drinking water, the acidity of wine, and the concentrations of toxic metals in factory effluents. In our laboratory, we are even using electrochemistry to provide information about the structure of the porous rocks in which petroleum is found. Electrodes are the places where chemistry converts to electricity, or vice versa. A typical electrode is the surface of a piece of metal in contact with a solution of salts and other chemicals dissolved in water. The interconversion of chemicals and electricity occurs when a special kind of chemical reaction a so-called

Monitoring leakage from underground storage tanks (UST) using spontaneous polarization (SP) method James W. Perry, Univ. New Hampshire, Durham, NH, Charles E. Corry, Golden, Colorado, Theodore Madden, MIT, Cambridge, Massachusetts Home Page Contents Index Comments? Summary Delineating and monitoring leakage from aging or ruptured underground storage tanks is both a common and expensive problem. Typically the site must be extensively drilled and numerous water samples taken and analyzed in order to delineate the contaminant plume. Remediation efforts often require that ground water sampling be continued frequently over several years. In contrast, discrete zones of hydrocarbon contamination around leaking storage tanks have been successfully mapped using spontaneous polarization (SP) methods at two separate locations in New Hampshire. Contaminated zones are distinct from their surrounding environment in SP surveys, and exhibit a negative potential whose magnitude is much greater than an order of magnitude above background levels despite severe cultural interference. One hydrocarbon plume associated with a leaking storage tank was located underneath asphalt paving behind a shopping mall in Stratham, NH. Three hydrocarbon plumes associated with such tanks located on Pease Air Force Base in Portsmouth, NH were successfully mapped using SP. In addition, remediation efforts at the former fire department training site at
