Acid-Base Theories
Chemistry ⇒ Acids, Bases, and Salts
Acid-Base Theories starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Acid-Base Theories.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Define a conjugate acid-base pair according to the Brønsted-Lowry theory.
Describe the main difference between the Brønsted-Lowry and Lewis definitions of acids and bases.
Describe the role of water in the self-ionization reaction: 2H2O ⇌ H3O+ + OH-.
Describe the term 'amphoteric' and give an example.
Explain why BF3 is considered a Lewis acid but not a Brønsted-Lowry acid.
Explain why Cl- is not a Brønsted-Lowry acid.
Explain why H2O can act as both a Brønsted-Lowry acid and base.
Explain why NH3 is considered a base according to both Brønsted-Lowry and Lewis theories.
