Hidrófilo

The transcript explains the dual nature of some molecules, which can be both hydrophilic and hydrophobic. This ambivalence provides useful properties, such as soap's ability to attract grease while dissolving in water.

What characteristic allows certain molecules to interact easily with water?

• Hydrophobic nature

• Hydrophilic nature

• Neutral charge

• High density

What term describes molecules that have both hydrophilic and hydrophobic properties?

• Dichotomous

• Bipolar

• Ambivalent

• Amphibious

How does the ambivalent nature of some molecules benefit their functionality?

• They can only dissolve in oil

• They repel both water and oil

• They can interact with both water and grease

• They are inert and do not react

Which of the following is an example of a molecule with both hydrophilic and hydrophobic properties?

• Soap

• Sugar

• Water

• Salt

What happens to soap when it interacts with water?

• It remains unchanged

• It solidifies

• It evaporates

• It dissolves
