Strength of Acids and Bases
Chemistry ⇒ Acids, Bases, and Salts
Strength of Acids and Bases 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 Strength of Acids and Bases.
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 9
A 0.1 M solution of NaOH and a 0.1 M solution of NH3 are prepared. Which solution will have a higher pH?
A student adds equal concentrations of hydrochloric acid and acetic acid to two separate beakers. Which solution will have a lower pH?
A student prepares two solutions: one of 1 M HCl and one of 1 M CH3COOH. Which solution will have more free hydrogen ions?
Define a strong acid.
Describe the difference between a weak acid and a dilute acid.
Describe what happens to the ions in a solution of a weak acid.
Describe what is meant by the term 'degree of ionization' in the context of acids and bases.
Explain the difference between a strong acid and a concentrated acid.
Explain why a strong acid conducts electricity better than a weak acid at the same concentration.
Explain why a weak base has a lower pH than a strong base at the same concentration.
Explain why the electrical conductivity of a strong acid is higher than that of a weak acid at the same concentration.
