Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

Kc for a Complex Ion Formation Objectives • • Find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion. Confirm the stoichiometry of the reaction. Background In the study of chemical reactions‚ chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield‚ limiting reactant‚ and percent yield—is the assumption that the reaction can consume all of one

EXPERIMENT NO. 6 DETERMINATION OF THE MOLAR VOLUME OF A GAS AND THE UNIVERSAL GAS CONSTANT Salve‚ Ryan Angelo TAB3‚ Group 6‚ Mr. John Kevin Paulo Biadomang Tabor‚ Frances Hermilyn March 8‚ 2013 ------------------------------------------------- I. Abstract This experiment is working with the ideal gas law‚ which is the summation of Boyle’s Law‚ where pressure is inversely proportional to volume‚ Charles’ Law‚ where the volume is directly proportional to temperature and Avogadro’s Law‚ where

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps
