Acid Base Neutralization

Front

What is an acid?

Back

An acid is a substance that donates protons (H⁺ ions) in a chemical reaction. Examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄).

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. Examples include sodium hydroxide (NaOH) and magnesium hydroxide (Mg(OH)₂).

Front

What is a neutralization reaction?

Back

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

Front

What are the products of the neutralization of HCl and NaOH?

Back

The products are sodium chloride (NaCl) and water (H₂O).

Front

What is a salt in chemistry?

Back

A salt is an ionic compound formed from the neutralization reaction of an acid and a base.

Front

What is the general equation for a neutralization reaction?

Back

The general equation is: Acid + Base → Salt + Water.

Front

What is the role of water in a neutralization reaction?

Back

Water is produced as a byproduct of the reaction between an acid and a base.

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

Back

The pH of the solution decreases, indicating increased acidity.

Front

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

Back

The pH of the solution increases, indicating increased basicity.
