[KMnO4] Calculation: = (0.104g of NaC2O4)(1 mol NaC2O4 /134.0g)(2 mol KMnO4 / 5 mol NaC2O4)(1/32.5 mL)(1000 mL /1L) = 0.00955 M KMnO4 2. Using the standardized concentration of KMnO4 calculated above to find the mass percentage of the oxalate ion Equation: Volume of KMnO4 reacted with Oxalate ion = (Vol of KMnO4 used in titration - Vol of KMnO4 used in blank titration) Titration Trial 1 Vf - Vi = VT 54.6 mL -28.1 mL = 26.5 mL 26.5 mL KMnO4 (1 L/ 1000 mL)(0.00955 M KMnO4 / 1L)( 5 mol C2O42-

Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s
