Unformatted text preview: Joshua Sipe Biology104 SectionM01 April 14, 2008 Title : Testing for Unknown Substances Abstract: The objective of this lab was to determine unknown substances through the use of different indicator tests. The experimental samples that were used were known as the Mayan II sample group which contained corn starch, table sugar, glucose and egg white in an unknown order. Using indicator tests each of the four samples were tested using the Biuret test, iodine test, Benedicts solution test and the Sudan IV test. These indicators test for proteins, reducing sugars, starches and lipids. Each sample was tested against the indicators and it was found that sample A was corn starch, sample B was glucose, sample C was egg white and sample D was table sugar. Hypothesis: The Mayan II sample containers can be determined by using indicator tests Procedure : The basis for this experimental procedure is outlined in Lab Manual Biol104 (Morris,TC3,2008) pgs.24-26 No change to procedures were made. The Mayan II sample was analyzed.(Morris,TC3,2008) pgs....
