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.
See sample questions for grade 11
Define a conjugate base.
Describe the main difference between the Arrhenius and Brønsted-Lowry definitions of acids and bases.
Describe the role of electron pairs in the Lewis acid-base theory.
Explain why NH3 is considered a base according to both Brønsted-Lowry and Lewis theories.
Explain why water is considered amphoteric.
Identify the Lewis acid in the following reaction: BF3 + NH3 → F3B←NH3
In the reaction: HSO4- + H2O ⇌ SO42- + H3O+, identify the conjugate acid of HSO4-.
In the reaction: NH3 + H2O ⇌ NH4+ + OH-, identify the Brønsted-Lowry acid.
State one major advantage of the Lewis acid-base theory over the Brønsted-Lowry theory.
