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

Determination of : Titration of a Weak Acid Introduction: We will be using the LoggerPro and LabPro in order to help us determine our data. The purpose of this experiment is to follow the changes of pH during the titration of an acid and a base in order to determine the of the weak acid‚ . is a constant for a given acid at a given temperature. In this experiment we determined the Ka using two different methods: 1) the measurement of the pH of a solution containing a known concentration of a weak acid‚ and 2)

given Solution using Titration Morphy Kuffour Mrs. Langlis‚ AP Chemistry C-D 9/24/2017 Purpose: Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in vinegar. Titration is an experimental technique

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

Titration test Alfredo Verzo III We have been provided with two samples of vinegar‚ one removed from a restaurant and one removed from a take-away. Trading Standards suspect these two establishments of watering down the vinegar. They need evidence that the samples contain less acid than the standard vinegar sample provided. What is the purpose of this? I’m a worker in the Trading Standards which carries out tests to see if restaurants and takeaways are watering down the vinegar. We will

to help narrow the selection of possible unknowns. Titrations using Na2S2O3 and HCl to determine percent cobalt and ammonia‚ respectively‚ are used. Silver nitrate is used to precipitate the chloride ions in the unknown‚ which can be measured to determine the percent composition of chloride in the unknown. The results from these three major analyses helped to draw the conclusion that the unknown is in fact [Co(NH3)6]Cl3. -2.0 Synthesis/Analysis of Cobalt-Amine-Halide Compund (Procedure 1‚ pgs 16-7))
