4.8 Intro to Acids and Bases - BL (AP Chemistry)

Front

What is a Bronsted-Lowry acid?

Back

A Bronsted-Lowry acid is a substance that donates a proton (H+) in a chemical reaction.

Front

What is a Bronsted-Lowry base?

Back

A Bronsted-Lowry base is a substance that accepts a proton (H+) in a chemical reaction.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a Bronsted-Lowry base gains a proton.

Front

What is a conjugate base?

Back

A conjugate base is the species formed when a Bronsted-Lowry acid donates a proton.

Front

What is the relationship between acids and their conjugate bases?

Back

When an acid donates a proton, it becomes its conjugate base.

Front

What is the relationship between bases and their conjugate acids?

Back

When a base accepts a proton, it becomes its conjugate acid.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH of the solution decreases, making it more acidic.

Front

What happens to the pH of a solution when a base is added?

Back

The pH of the solution increases, making it more basic.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is an amphoteric substance?

Back

An amphoteric substance can act as both an acid and a base depending on the reaction.
