  • Electrolytic Synthesis Lab Report

    Similar to strong acids, strong bases are also good conductors of electricity due to their large concentration of ions. Examples of strong bases are calcium hydroxide and barium hydroxide. Weak bases produce a very low concentration of hydroxide ions, and thus, are poor conductors of electricity. Ammonia and ethylamine are examples of weak bases. As shown in the reaction below, the position of equilibrium gives the reactants…

  • Food Irradiation Research Paper

    IRRADIATION Food irradiation is the processing of food products by ionising radiation in order to control food borne pathogens, reduce microbial load and insect infestation, inhibit the germination of root crops, and extend the durable life of perishable produce (International Consultative Group, 1991). Application of ionizing radiation results in the radiolysis of water. This triggers the development of species such as OH−, hydrated electron and H+, which can then induce several chemical…

  • Differences And Similarities Between Dmitri Mendeleev And The Modern Periodic Table

    The periodic table is a very identifiable symbol in everything science. There is one hanging in almost every chemistry class. But, the one we know is not what it always was. Before our modern periodic table there was the periodic table that Dmitri Mendeleev constructed. There are many differences and similarities between the Modern Periodic Table and Mendeleev’s Periodic Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered…
