    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 cells 2014). Oxidation always occurs simultaneously to reduction and the process of this electron transfer is named a redox reaction (A.Olivier 2010). In this

    1085 Words  | 5 Pages

    negative terminal of the battery is the cathode, and the anode is the positive terminal. While Sir William Crookes was experimenting, he saw a ray of light going through the tube. Later, it was discovered that it was radiation that was traveling from the negative terminal, the cathode, to the positive terminal, the anode. This ray is known as the cathode ray now. From this discovery,

  • Social Cognitive Theory Of Aggression Essay

    1301 Words  | 6 Pages

    Aggression is a spoken or physical behavior that causes intentional harm to a person. There are many different theories that argue what the cause of aggression is but this can be divided into two major types: people who think that aggression is inborn and those that view it as a learning behavior. The Social cognitive theory states that we learn behaviors through observation and modeling and this could be implied that we learn aggressive behaviors through observing and imitating others. The Social

    The zinc acts as the anode and the copper acts as the cathode. Copper has a higher electronegativity than zinc, so the bonding electrons in zinc leave and flow into the copper. However, this reaction would not be possible without the lemon in the experiment, which acts as an electrolyte because it contains citric

    The homogeneous solution was contained of Na2H2EDTA.2H2O, KH2PO4 and CaCl2 on 0.25/0.25/0.15 M. Water reduction at cathode to form OH- ion is very substantial in formation of hydroxyapatite. The OH- ions causes the release of Ca2+ ions and change the equilibrium phosphate for the formation reaction of HA. The problem of electrochemical method is OH- ions move away from the cathode due to the difference in charge. This condition decrease the productivity of the formation of HA because OH- ions react

    electrodes and an electrolyte is needed. Electrodes are the conductors of electricity that are in contact with the non-metallic part of the circuit (which in this case is the solution) (Bylikin & Horner, 2014). There are two types of electrodes: anode and cathode which are positively and negatively charged respectively. An electrolyte is a liquid or solution that can carry an electric current through it (BBC Bitesize). In solid form, sodium chloride can’t be electrolyzed as the ions are held and arranged in

  • Christian Huygen Theory Of Light Essay

    1349 Words  | 6 Pages

    Light is a component of the electromagnetic spectrum, the spectrum is that the assortment of all waves, that include light, Microwaves, Radio waves, X-Rays, and Gamma Rays. In the late year’s of 1600s, vital problems were raised, asking if light is made up of particles, or is it waves .? Sir Isaac Newton, held the idea that light was created from little particles. In 1678, Dutch scientist, Christian Huygens, believed that light was made up of waves moving up and down perpendicular to the direction

    Thomson discovered the electrons which has a huge impact of the existing atomic model of Dalton. From his cathode ray experiment, he learned and discussed about the existence of electrons. Cathode ray experiment explored on cathode ray tubes which are vacuum tubes that consist of one electrode one each side of the tube, altogether consisting of two electrodes, when one of the electrodes or the “cathode” launches electron at the other electrode or “anode”, the voltage is added to the system. While Thomson

    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

    00E-6 Calculation 3: Cathodic scan of unknown concentration X=(3.00E^(-5)+1.00E^(-5))/(4.00E^(-6) )= 10mM For Table 2a, the value for the cathode unknown is 10 mM while the anode is 1.53 mM. There is an 85% difference between the two which is most likely to be caused by the 10mM outlier. Now if the 10 mM data values are removed the results are 5.2 mM for the cathode and 4.5 mM for the anode. This is a 15% difference between the two calculated unknowns. Although the percent difference is not idea, it

    it also provides a negative charge to the uncharged molecule. The SDS-PAGE enables the separation of proteins based on their sizes. The larger the size of the protein, the harder it is to travel through the gel thus heavier proteins stay near the cathode side of the gel. For this experiment, a software named Gel Analyzer was used in order to obtain the molecular weight of the unknown proteins with the help of a protein ladder with known molecular weight and protein concentration. The software also
