Potentiometric Titration of Sodium Carbonate Otieno O. Victor University of Detroit Mercy Quantitative Analysis Lab CHM 3880 Fall 2011 Partner: Edwin Gay Abstract The PH at each point during the titration of sodium carbonate unknown sample was determined. An Unknown sample of Na2CO3 was titrated with a standard HCL solution. In addition to titration‚ the pH at each point of titration was measured using PH meter. The % of the unknown Na2CO3 was 25.83% Introduction1 The purpose of this experiment

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

Floyd Askew 3/19/13 CHEM 1211L Lab Report Introduction The purpose of this lab is to use volumetric analysis to determine the concentration of unknown substances. A sodium hydroxide solution is standardized to assist in finding the concentration of an acetic acid. An indicator must be used to pin point the equivalence point‚ the point in which 1 mole of a substance is equal to 1 mole of another. When that is found‚ we can determine the concentration.

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

The purpose of the lab was to construct a graph of sugar content versus density for 5 sugar solutions and to determine the sugar content of the 5 beverages using graphical analysis. The hypothesis was that if a beverage has more sugar‚ then it will be more dense. The results of the lab included the densities of all the solutions and beverages‚ which was then graphed. Then‚ using the graph‚ the sugar content for the beverages was determined and a rank of the beverages was created. From lowest sugar
