of a Commercial Bleach Purpose To perform a redox titration. To determine the amount of hypochlorite ion present in commercial bleach. Introduction Many commercial products‚ such as bleaches and hair coloring agents‚ contain oxidizing agents. The most common oxidizing agent in bleaches is sodium hypochlorite‚ NaClO (sometimes written NaOCl). Commercial bleaches are made by bubbling chlorine gas into a sodium hydroxide solution. Some of the chlorine is oxidized to the hypochlorite ion‚

about the question and the different reasons that organisations use internal and external change agents. Indeed I have written something about this in the latest edition of our book Making Sense of Change Management: “Some organizations rely on outside help whilst others believe that they have the change agency capacity in-house. Although the core competencies of internal and external change agents are similar it is worth considering some of the differences between the two‚ partly so one can consider

Talent Agency Act (TAA) [is] the law enacted in 1978 that requires a person to have a license if they are acting as an agent… the TAA defines a talent agent as ‘a person or corporation who engages in the occupation of procuring‚ offering‚ or attempting to procure employment for an artist’ ” (Forbes‚ 2013). In this context‚ “artist” also refers to athletes represented by talent agents. The TAA effectively restricts any other entity from legally representing athletes in any compensation negotiation. In

Purpose The purpose of this lab is to identify the different features that come about by using oxidation reduction and recording the observations‚ these tests will help determine the specific qualities each solution has. Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation

INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic acid is back titrated in the presence of a suitable indicator. 2Cr2O72- + 16 H+ + 3C = 4Cr3+ + 8H20 +3CO2 CHEMICALS AND REAGENTS: i) 1N K2Cr2O7 : Dissolve 49.04 g K2Cr2O7 (dried at 105ºC)

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:
