If fat is present, a mixture of ethanol and water becomes __________ __________ in colour. What words complete the sentence?

If fat is present, a mixture of ethanol and water becomes cloudy white in color.

This phenomenon occurs due to the emulsification that happens when fat is added to the ethanol-water mixture. Ethanol has the ability to dissolve both polar and non-polar substances to some extent. When fat is introduced, it does not completely mix but rather forms small droplets dispersed throughout the liquid. This dispersion leads to increased light scattering, which manifests as a cloudy or milky appearance. The degree of cloudiness can also vary depending on the concentration of fat in the mixture, illustrating an important characteristic of emulsions and the interactions between polar and non-polar substances.
