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

short measurement times. With a high accuracy mass flow sensor the fuel consumption is determined continuously and via direct mass flow measurement in kg/h. The density does not have to be determined in addition to the direct determination of the gravimetric or specific fuel consumption like in volumetric measurement methods. The fuel consumption can thus be determined to an accuracy of 0.12% for the whole system under real test bed conditions. With the FlexFuel version‚ up to 100% alcohol and biodiesel

chromatography)‚ HPLC‚ is a chromatographic technique used to separate the components in a mixture‚ to identify each component‚ and to quantify each component. HPLC is considered an instrumental technique of analytical chemistry (as opposed to a gravimetric technique). In general‚ the method involves a liquid sample being passed over a solid adsorbent material packed into a column using a flow of liquid solvent. Each analyte in the sample interacts slightly differently with the adsorbent material‚

Analysis Finding the Percentage Composition of Nickel in an Unknown Compound Introduction: This section of lab was about using analytical chemistry and learning how to identify the amount of nickel in an unknown substance. The purpose was to use gravimetric analysis to quantitatively separate and weigh insoluble reaction products as well as utilize the mole method to compute the amount and percentage of nickel in an unknown nickel sample. The chemical reaction that took place involved the reaction

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the gravimetric analysis technique. The solution of Na2SO4 (0.5 M) and BaCl2 (0.1 M) were chosen in this experiment. The equation was used: Na2SO4 (aq) + BaCl2 (aq) → BaSO4 (s) + 2 NaCl (aq). However‚ in this reaction‚ cation Ba2+ and anion (SO4)2- play the main
