The colorless solution made from an unknown white solid turned blue litmus red. The flame test showed no color. Addition of NaOH produced a white, gelatinous precipitate but no odor. Addition of HCl produced no bubbles. No precipitate formed after adding AgNO, and Pb(NO,),. Identify the unknown from the list of possibilities in the Introduction to this experiment.

For breakfast, the nihilistic Rick Sanchez ate 100 g of cereal mixed with 20 g of milk. A 1.500 g sample of the same cereal was analyzed using the Kjeldahl method, and the liberated NH3 was distilled into 50 mL of a 0.0227 M HCl solution, and back-titrated with 2.85 mL of 0.0112 M NaOH solution. A 1.100 g sample of milk was also analyzed, and the liberated NH3 was distilled into 55 mL of a 0.0234 M HCl solution, and back-titrated with a 3.10 mL of 0.0121 M NaOH. Use the values: MM N=14.07 g/mol. meat= 6.25 dairy= 6.38 cereal= 5.70 What is the % protein in the cereal sample? What is the % protein in the milk sample?
