Question

An emulsion cannot be broken by __________

and ___________.

• A. freezing
• B. heating
• C. adding emulsifying agent
• D. adding more amount of dispersion medium

Answer 1

Answer: (C), (D)

adding more amount of dispersion medium

Emulsions are liquid-liquid colloidal systems. So, they cannot be broken by adding more dispersion medium and emulsifying agents as on adding dispersion medium they become dilute and on adding emulsifying agents they become stable. Hence, options $\left(B\right)$ and $\left(D\right)$ are correct.
