Prelab 2//2/09 Indigo Carmine is a blueish dye that is particularly used in Ph Testing but is commonly used in kidney screenings to stain the Negri bodies in a properly working kidney. It differs from indigo in the sense that they are two different colors as well as their property make up. Where regular indigo has a molecular makeup of C 16 H 10 N 2 O 2, indigo carmine is a little more complex with the make up of C 16 H 8 N 2 Na 2 O 8 S 2 . How many products of the reaction are possible? 5. Describe how the concept of reaction rate can explain how the reaction can be "managed" to produce a desired outcome. The reaction rate of an experiment is the overall change of the concentration of the sample over a given time period. This can be

Unformatted text preview: manipulated to an outcome that one would like to see by selecting specific times that produce a concentration output of something relative to the overall success of the experiment. 6. Describe how absorption spectroscopy will be used to determine the percent yield of the reaction. Absorption spectroscopy can determine percent yield by telling you the relationship between the concentration and the absorption; you can compare these results to what you were supposed to get in your experiment. By knowing what your initial value you are trying to find, and comparing it to the measured absorption value that the spectroscopy tells you, percent yield can be calculated....
