GCSE Chemistry - The pH Scale & Strong vs Weak Acids (Higher Tier) #35

The video explains the difference between strong and weak acids, focusing on their ionization in aqueous solutions. Strong acids fully ionize, while weak acids only partially ionize, establishing an equilibrium. The video also clarifies the distinction between acid strength and concentration, emphasizing that strength refers to ionization extent, while concentration is about the amount of acid in a solution. Finally, it covers pH, a measure of hydrogen ion concentration, noting that a lower pH indicates higher hydrogen ion concentration.

What defines a strong acid and how does it differ from a weak acid?

What is the significance of the equilibrium in the ionization of weak acids?

How does the concentration of an acid affect its pH?

Explain the relationship between pH and the concentration of hydrogen ions.

Discuss how the dissociation of strong and weak acids affects the overall concentration of hydrogen ions in a solution.
