Intro to Acids and Bases

Front

What is an acid?

Back

An acid is a substance that donates protons (H⁺ ions) in a chemical reaction.

Front

What is a base?

Back

A base is a substance that accepts protons (H⁺ ions) or donates hydroxide ions (OH^-) in a chemical reaction.

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 a strong acid?

Back

A strong acid is an acid that completely dissociates in water, releasing all of its protons.

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, meaning not all of its protons are released.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in water, producing a high concentration of hydroxide ions (OH^-).

Front

What is a weak base?

Back

A weak base is a base that partially dissociates in water, resulting in a lower concentration of hydroxide ions (OH^-).

Front

What is the Bronsted-Lowry theory?

Back

The Bronsted-Lowry theory defines acids as proton donors and bases as proton acceptors.

Front

What is the difference between an Arrhenius acid and a Bronsted-Lowry acid?

Back

An Arrhenius acid produces H⁺ ions in water, while a Bronsted-Lowry acid is defined by its ability to donate protons.

Front

What is neutralization?

Back

Neutralization is a chemical reaction between an acid and a base that produces water and a salt.
