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 12
A solution has a pH of 12. Is it likely to be a strong acid, weak acid, strong base, or weak base?
A student adds equal concentrations of HCl and CH3COOH to water. Which solution will have a lower pH?
A student prepares two solutions: 0.1 M HCl and 0.1 M NH3. Which will have a higher concentration of ions?
Calculate the pH of a 0.001 M HCl solution.
Calculate the pOH of a 0.01 M NaOH solution.
Define the term 'acid dissociation constant' (Ka).
Describe how the strength of an acid affects its electrical conductivity in aqueous solution.
Describe the difference between a strong acid and a concentrated acid.
Explain why HF is a weak acid even though it is a halogen acid.
Explain why NaOH is considered a strong base.
Explain why the strength of an acid is not the same as its concentration.
If the Kb of a base is very small, what does this indicate about its strength?
What is the relationship between Ka and Kb for a conjugate acid-base pair?
