Question

Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation
(Salting Out)

After filtration, 30.0 mL of the filtrate was obtained, and the solution was brought from 0% to 40% saturation by adding the required amount of powdered ammonium sulfate, (NH4)2SO4.

Why is there a need to gradually add the ammonium sulfate to the sample?
