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.

Fill in the blank: A ______ base only partially ionizes in water.
Fill in the blank: A ______ solution contains a small amount of solute in a large amount of solvent.
Fill in the blank: A base that completely dissociates in water is called a ______ base.
Fill in the blank: The concentration of an acid refers to the amount of acid ______ in a given volume of solution.
Is it possible for a weak acid to be concentrated?
True or False: A concentrated acid is always a strong acid.
True or False: A dilute solution of a strong acid can still be dangerous.
True or False: A strong acid always has a lower pH than a weak acid at the same concentration.
