    Electrochemistry is the study of reactions in which charged particles (ions or electrons) appear in two phases of matter, such as the metallic phase (the electrode) or aqueous phase (the electrolyte). (Lower 2004) These reactions involve the transfer of electric charges between the electrodes and the electrolyte. These cells have two electrodes which are named the anode and the cathode. The anode is the electrode where oxidation occurs and the cathode is the electrode where reduction occurs (Electrochemical

  • Electrolysis In Chemistry Ia

    2800 Words  | 12 Pages

    Chemistry IA Background information: Introduction: Electrolysis it’s a chemical process that when you pass an electric current into a solution or a liquid that contains ions to separate substances back to their original form. The main components that are required for electrolysis to take a place are:  Electrolyte: it’s a substance that when dissolved in water it ionize and then it will contain free moving ions and without these moving ions the process of electrolysis won’t take place.  Direct

  • Cathode Ray Experiment Research Paper

    1085 Words  | 5 Pages

    Ordinary observations were a key to new discoveries which later led to the discoveries in the 1800s. The vacuum pump, which was a tube with electricity passed through with only some air particles, was a large part of finding and studying the relationship between charge and mass. There were metal electrons that were attached on the opposite sides of the tube, and the negative terminal of the battery is the cathode, and the anode is the positive terminal. While Sir William Crookes was experimenting

  • Capacitors Lab Report Conclusion

    1687 Words  | 7 Pages

    Capacitors are two conducting plates separated by an insulating material. So when a voltage is applied across the plates, the battery works on the plate to separate the negative and positive charges on the capacitor. In lab 21 we will observe this type of charge in snap circuits by using the snap circuit kit from our lab and a stopwatch. In part two of this lab, I observed how the relationship how current, voltage and resistance are used to through a system in regards to Ohm’s Law. Introduction

  • Task 1. Explain How A Capacitor Is Constructed?

    791 Words  | 4 Pages

    Task 1 Explain how a capacitor is constructed? You can imagine a capacitor being a sandwich, two metal plate (electric) that sandwich the dielectric acting as an insulator keeping the two metal plates from touching each other. The dielectric can be made from many different materials like silicon, silicon nitride, aluminium oxide and zirconium oxide to name a few, they all have different values and properties. Which is used depends on the purpose of the capacitor and type of capacitor. The electric

  • Polysulfone Case Study

    1048 Words  | 5 Pages

    4) Polysulfone (PSU)[6] The foaming behavior of PSU foams is very similar to that of COC discussed above. PSU is potentially useful for high temperature applications. Cell nucleation density as high as 1015 cells/cm3 can be achieved with PSU foams. Thus cell sizes in the nanocellular range (20-30 nm) can be achieved. Foaming is carried out by the solid state foaming process. CO2 solubility in PSU CO2 solubility in PSU increases with a decreasing foaming temperature. PSU samples were foamed in

  • Polar Bears: Thick Layer Bear

    1254 Words  | 6 Pages

    Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called

  • Strontium Ferrite Synthesis Lab Report

    883 Words  | 4 Pages

    In this project, titanium(IV) ethoxide, Ti(CC2H5)4, Cobalt(II) nitrate, Co(NO3)2.6H2O, Iron(III) nitrate-9-hydrates, Fe(NO3)3.9H2O, and strontium nitrate, Sr(NO3)2 are needed to prepare both non-substituted strontium ferrite and substituted strontium ferrite. In this case, non-substituted strontium ferrite acts as a control in this project to compare with the characteristics of cobalt-titanium substituted strontium ferrite. The main objective of this project is to compare the effect of substitution

    Luigi Galvani Thesis Statement today you will know about a realistic scientist that made an impact on the author of Frankenstein. Luigi Galvani was an excellent anatomist, was born to by a middle class family in Bologna, Italy on September 9,1737. His family only had money to send one child to college so Luigi Galvani went. At first Galvani wanted to be a priest but in 1755 he entered the University of Bologna following his father 's footsteps in medicine instead. He graduated in 1759. In 1762

    The use of catalysts by mankind, dates back thousands of years, in processes such as wine- or bread-making. Their reaction scope is enormous and thus, they play an important role not only in natural processes, but in commercial processes as well. The latter include among others, the commercial production of chemicals, medicines and foods. According to IUPAC, a catalyst is a substance that has the ability to increase the reaction rate, when added to a reaction, without itself getting consumed in
