What Is The Bronsted Lowry Theory

The video tutorial explains the definitions of acids and bases, focusing on the Bronsted-Lowry theory. It contrasts this with the Arrhenius theory, highlighting how substances like ammonia can act as bases without releasing hydroxide ions. The tutorial covers testing for acids using indicators, the dissociation of hydrochloric acid, and the concept of amphoteric substances. It concludes with a summary of the Bronsted-Lowry theory, emphasizing proton transfer in acid-base reactions.

According to the Arrhenius theory, what is a base?

• A substance that releases protons in solution

• A substance that releases hydroxide ions in solution

• A substance that accepts protons in solution

• A substance that has a pH lower than 7

What is the main focus of the Bronsted-Lowry theory?

• The release of hydroxide ions

• The transfer of protons

• The color change in litmus paper

• The pH level of a solution

In the Bronsted-Lowry theory, what role does water play when it accepts a proton?

• It acts as an acid

• It acts as a base

• It acts as a neutral substance

• It acts as a catalyst

What term describes substances that can act as both acids and bases?

• Neutral

• Catalytic

• Alkaline

• Amphoteric

According to the Bronsted-Lowry theory, what is the requirement for a substance to be considered a base?

• It must release hydroxide ions

• It must have a pH greater than 7

• It must turn red litmus paper blue

• It must accept protons
