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?

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.

A 0.1 M solution of HCl is _______ (stronger/weaker) than a 0.1 M solution of acetic acid.
A 0.1 M solution of NaOH has a pH of approximately _______.
Fill in the blank: A _______ acid is one that ionizes completely in aqueous solution.
Fill in the blank: The higher the concentration of H+ ions in a solution, the _______ the pH value.
State whether the following statement is true or false: A 1 M solution of acetic acid is a strong acid.
True or False: A concentrated solution of a weak acid can have a lower pH than a dilute solution of a strong acid.
True or False: The concentration of an acid tells us how much acid is present in a given volume of solution.
True or False: The pH scale is a measure of acid and base strength.
