performed this test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants

Identifying an Unknown Aldehyde or Ketone Introduction The purpose of this lab is to identify an unknown aldehyde or ketone substance using chemical tests. The chemical tests used in this experiment are solubility‚ Schiff‚ Bisulfite‚ and Iodoform tests. Also‚ a 2‚4-dinitrophenylhydrazone derivative synthesis reaction will be completed from which a melting point will be obtained. The chemical test results and the melting point analysis will be compared to the table of compounds given to find the

Hot rods are vintage American cars that are modified for straight line speed. Young men who wanted speed‚ built these cars in their backyards. In the early years of hot rodding‚ 7‚500 people were killed in car wrecks‚ however hot rods have made positive impacts also. For 80 years‚ hot rods have caused the automakers to create the sports car‚ and muscle car. Hot rods have had a big influence on the car industry that a lot of people are not aware of. Hot rods got their start in the early 1920s in southern

Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance equal to
