- Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation(Salting Out) Egg whites contain about 88.5% water and about 10% proteins, from which ovalbumin is the major component. The eggs were cracked open, and the egg whites were separated carefully from the yolk. Stirring of the egg whites was done to break up the membrane. This was followed by filtration through cheesecloth, where a clear filtrate was obtained. About 40.0 mL of the filtered undiluted egg white was measured, and 0.10 mL of 1 M acetic acid was slowly added for every 1.0 mL of egg white with constant stirring. A turbid mixture with few amounts of white precipitate may be expected to form. These may be removed by filtering the mixture using a cheesecloth 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 After adding ammonium sulfate, the mixture was allowed to stand…Why mixture of solvents such as ethyl acetate with 5% acetic acid is used as a solvent/mobile phase for developing TLC?Utilizing Bentham's "Felicific Calculus" step-by-step, give a justification in practicing proper use of facemasks outdoors as a health protocol during this time of COVID-19.
