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 10

A student adds equal concentrations of HCl and CH₃COOH to water. Which solution will have a lower pH?
A student tests two solutions with universal indicator. Solution A turns red, and Solution B turns orange. Both are acids. Which is likely the stronger acid?
Describe how the pH value indicates the strength of an acid or base.
Describe the relationship between the strength of an acid and its electrical conductivity in aqueous solution.

Fill in the blank: The pH of a strong base is usually _______ than that of a weak base at the same concentration.
True or False: A dilute solution of a strong acid is still a strong acid.
True or False: A strong acid always has a lower pH than a weak acid at the same concentration.
True or False: A strong base dissociates completely in aqueous solution.
True or False: The concentration of an acid determines its strength.
