For question 2, be the critiquing lab partner. For questions 3-6, assume the first person role as if the results were your own. Question 7 requires deep thinking.Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation (Salting Out) The computed amount of powdered ammonium sulfate was added to the egg white sample portion byportion with constant stirring while submerged in an ice bath. The solution is expected to become moreturbid, and a white precipitate is expected to form. The resulting mixture was then filtered using a cheesecloth. The residue was discarded, and 30.0 mL of thefiltrate was brought from 40% to 60% saturation by adding the required amount of powdered ammoniumsulfate in the same manner as the previous addition. After adding ammonium sulfate, the mixture was allowed to stand with occasional stirring for 30 minutes inan ice bath. The formation of a white precipitate is expected to happen QUESTION: Explain the significance of allowing the mixture to be submerged in an ice bath for a given time.
