Question

Based completely on standard advanced physical chemistry texts, which of the following definitive statements regarding the inherent stability and deliberate ultimate destruction of highly specific commercial colloidal systems are strictly theoretically true?

Answer: A,C,D

💡 Solution & Explanation

Statement A correctly details and lists standard physical destructive demulsification methods perfectly. Statement B is completely universally false; complex emulsion droplets frequently deeply acquire a high charge directly from the active emulsifier or stray aqueous ions and *can* definitely heavily be forcefully coagulated simply by adding strong active electrolytes. Statement C correctly defines the specific strict standardized purpose of the exact Gold Number. Statement D correctly physically strictly applies Bancroft's rule (entirely oil-soluble active emulsifiers heavily functionally make oil the continuous outer phase, dependably creating stable W/O emulsions).
