Principle
When egg white is heated, the protein contained in it coagulates. Protein flocculates out on the addition of alcohol, solutions of heavy metals or small quantities of acids. When protein flocculates out, it loses its natural composition. The protein is denatured. The experience of the students can be used as an entry to this problem. Boiling eggs or the flocculation of milk offer opportunities for a discussion on this subject.
