Neutralization Reactions Worksheet

What is a neutralization reaction?

• A reaction between an acid and a base to form water and a salt.

• A reaction between two acids to form a base.

• A reaction between two bases to form an acid.

Which of the following is an example of a neutralization reaction?

• HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

• NaCl(aq) + H₂O(l) → HCl(aq) + NaOH(aq)

• H₂O(l) + CO₂(g) → H₂CO₃(aq)

• NaOH(aq) + H₂SO₄(aq) → Na₂SO₄(aq) + H₂(g)

What ion does an acid produce when dissolved in water?

• H⁺

• OH⁻

• Na⁺

• Cl⁻

What ion does a base produce when dissolved in water?

• OH⁻

• H⁺

• Na⁺

• Cl⁻

Which statement best describes a salt in the context of a neutralization reaction?

• An ionic compound made from the cation of a base and the anion from an acid.

• A substance that produces H⁺ ions in water.

• A substance that produces OH⁻ ions in water.

• A compound that only contains water molecules.

Given the reaction HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l), which product is the salt?

• NaCl(aq)

• H₂O(l)

• HCl(aq)

• NaOH(aq)

Why are the definitions of acid, base, and salt described as "oversimplified" in the material?

• Because more detailed definitions will be provided later in the concept.

• Because they are incorrect.

• Because they only apply to gases.

• Because they are not used in chemistry.

What is an Arrhenius acid?

• A chemical compound that increases the concentration of hydrogen ions in an aqueous solution.

• A chemical compound that decreases the concentration of hydrogen ions in an aqueous solution.

• A chemical compound that increases the concentration of hydroxide ions in an aqueous solution.

• A chemical compound that does not affect ion concentration in an aqueous solution.

What happens when an acid ionizes in water?

• It increases the amount of hydrogen ions present.

• It decreases the amount of hydrogen ions present.

• It increases the amount of oxygen molecules present.

• It decreases the amount of water molecules present.

What is ionization in the context of acids?

• When ions form from a covalent compound.

• When ions form from an ionic compound.

• When molecules evaporate from a solution.

• When acids lose their color in water.
