    COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the metal ion center to form

    Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also

    DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper

    Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take
