In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 5. In the next test, she finds that tubes 3, 4, and 5 are positive for nitrogen but only tube 3 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 4 contains a high percentage of phosphate. In the final test the student shows that compound 1 is hydrophobic.
