Acetic Acid Properties and Interactions

The video explains the solubility of acetic acid (CH3COOH) in water, highlighting its polar nature due to the electronegative oxygen atoms. This polarity allows acetic acid to dissolve well in water, a polar molecule, through dipole interactions. The video demonstrates how water molecules surround and interact with acetic acid, forming a homogeneous solution.

What is the chemical formula for acetic acid?

• CH3COOH

• C2H5OH

• H2SO4

• NH3

Why is acetic acid considered a polar molecule?

• It has a symmetrical structure.

• It contains a carboxylic acid group.

• It has electronegative oxygen atoms.

• It is a non-polar solvent.

What role do the oxygen atoms play in acetic acid's solubility?

• They attract hydrogen atoms in water.

• They make acetic acid non-polar.

• They repel water molecules.

• They have no effect on solubility.

How do water molecules interact with acetic acid?

• They form covalent bonds with acetic acid.

• They align with the positive and negative charges of acetic acid.

• They repel acetic acid molecules.

• They do not interact with acetic acid.

Which part of the acetic acid molecule is attracted to the hydrogen in water?

• The oxygen atom

• The hydrogen atom

• The carbon atom

• The entire molecule

What happens when water molecules surround acetic acid?

• They form a heterogeneous mixture.

• They create a solid precipitate.

• They dissolve acetic acid completely.

• They separate into layers.

What type of solution is formed when acetic acid dissolves in water?

• Homogeneous solution

• Colloid

• Suspension

• Heterogeneous solution

Why can acetic acid mix well with water?

• Because both are non-polar.

• Because acetic acid is a gas.

• Due to dipole interactions.

• Due to ionic bonding.

What is the main reason for acetic acid's solubility in water?

• Its large molecular size.

• Its ionic structure.

• Its ability to form hydrogen bonds.

• Its non-polar nature.

What is the result of the dipole interactions between acetic acid and water?

• No interaction occurs

• Dissolution of acetic acid in water

• Complete separation of molecules
