Acid and Base Strength and Concentration
Chemistry ⇒ Acids, Bases, and Salts
Acid and Base Strength and Concentration 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 and Base Strength and Concentration.
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
A student adds 0.1 mol of HCl to 1 L of water and 0.1 mol of CH3COOH to another 1 L of water. Which solution will have a lower pH?
A student prepares two solutions: Solution A is 0.1 M HCl, and Solution B is 1 M CH3COOH. Which solution has a higher concentration of H+ ions?
Calculate the number of moles of H+ ions in 500 mL of 0.2 M HCl solution.
Calculate the pH of a 0.01 M NaOH solution.
Calculate the pOH of a 0.001 M NaOH solution.
Define the term 'acid strength'.
Define the term 'base strength'.
Describe how you would prepare a dilute solution from a concentrated acid in the laboratory.
Explain the difference between a strong acid and a concentrated acid.
Explain why a dilute solution of a strong acid can still be more corrosive than a concentrated solution of a weak acid.
Explain why ammonia (NH3) is considered a weak base.
