The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was determined to be 2-heptanone. Introduction Extraction is one way of purifying a substance. In an extraction‚ a solute is transferred from one solvent to another. Extractions depend on polarity and solubility; polarity is the separation of charge caused by a difference

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.

Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

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
