    Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

    INTRODUCTION Alkaline phosphatase catalyses the hudrolysis of p-nitrophenyl phosphate (a synthetic substrate) at an optimum pH of 10.0 with the liberation of p-nitrophenol. The substrate is colourless‚ but the product p-nitrophenol is yellow in alkaline solution‚ absorbing maximally at 405 nrn. Thus a convenient assay for this enzyme involves monitoring the change in absorbance of the reaction medium at 405 nm. Exergonic (i.e energy producing reactions) exhibit a negative free energy change

    On the other hand‚ in the article When Self-Determination Runs Amok by Callahan‚ he explores the concept of active and passive euthanasia‚ but for him it’s not so much of an ethical debate – as it is for Rachels – but rather divides his theory into three parts. First‚ he speaks about the legitimate conditions under which an individual may kill another. Secondly‚ he speaks about meaning and limits of self determination‚ arguing that this type of view only leads to a "idiosyncratic view of the good

    Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e-  Mn2+(aq) + 4H2O Theory:

    Freewill vs. Determinism Good vs. Evil   What makes a decision evil is when it is made completely with regard to others. What makes a decision good is when the person who made it can look back and feel like what he choose was wholly right. It is completely up to a person whether or not they take others into consideration or even decide to look back long enough to care‚ just like it is up to that person to choose where they go in life. Whether it’s up the "good path" or down the "evil path" isn’t
