Hydronium Ion and Acid Properties

The video explains the behavior of chloric acid (HClO3) in water, identifying it as a weak acid. It discusses the ionization process where only some hydrogen ions dissociate, leading to an equilibrium state. The formation of the hydronium ion (H3O+) is also covered, highlighting its equivalence to H+ in chemistry.

What is the nature of HClO3 when dissolved in water?

• Strong base

• Neutral compound

• Weak acid

• Strong acid

Why is HClO3 considered a weak acid?

• It does not dissolve in water

• It forms a strong base in water

• It is not listed among the strong acids

• It completely dissociates in water

What happens to HClO3 in water?

• It fully ionizes into H+ and ClO3-

• It remains as HClO3

• It forms a precipitate

• It partially ionizes into H+ and ClO3-

What is the charge on the hydrogen ion (H+) when HClO3 ionizes?

• +2

• 0

• +1

• -1

What is the state of the solution when HClO3 is in water?

• Precipitated

• Dynamic

• Equilibrium

• Static

What does 'aq' signify when written after ions?

• Solid state

• Gaseous state

• Liquid state

• Aqueous or dissolved in water

What is the hydronium ion?

• OH-

• H3O+
