  • The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis
    The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems,...

The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons, being negative, reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons,...

    Standardize a solution of potassium manganate(VII) by an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation, oxidation has occurred (electrons have been lost); if the oxidation number...

    SELECTED REDOX REACTIONS RESULTS AND DISCUSSION Oxidation-Reduction reaction also known as redox reaction is a process in which there’s a net movement of electrons between reacting species. These types of reactions involve two separate elementary reactions: one that loses electrons and another that gains the electrons that was lost. Gaining of electrons is referred to as Reduction reaction (the species that undergoes reduction is called as oxidizing agent) while losing of electrons is...

    Results and Discussion Potassium permanganate, KMnO4, is widely used as an oxidizing agent in volumetric analysis. In acid solution, MnO4- ion undergoes reduction to Mn2+ ion as shown in the equation: 8 H+(aq) + MnO4-(aq) + 5e- → Mn2+(aq) + 4 H2O(l). Since the MnO4- ion is violet and the Mn2+ ion is nearly colorless, the end point in titrations using MnO4- as the titrant can be taken as the first permanent pink color that appears in the solution being titrated.1 The number of moles of...
