4.2.2 Neutralization of acids and salt production

• What is the chemical reaction called when an acid and a base are combined to form a salt and water?

  Neutralization
• In neutralization reactions, an acid reacts with a base to form a salt and water.


  True
• In neutralization reactions, water is formed when H⁺ ions combine with OH⁻ ions to form H₂O
• Sodium hydroxide (NaOH) is an example of a base in neutralization reactions.


  True
• Neutralization reactions reduce the acidity and alkalinity of a solution, bringing its pH closer to neutral
• What are the products formed in a neutralization reaction?

  Salt and water
• In a neutralization reaction, an acid donates protons (H⁺) and a base accepts them, forming water and a salt
• Steps in the neutralization reaction process

  1️⃣ Acid donates protons (H⁺)

  2️⃣ Base accepts protons (OH⁻)

  3️⃣ Water (H₂O) is formed

  4️⃣ Remaining ions combine to form a salt
• The salt formed in a neutralization reaction consists of the cation from the base and the anion from the acid
• What gas is produced in an acid-metal neutralization reaction?

  Hydrogen
• Neutralization reactions are used in everyday applications such as treating acid reflux.

  True
• In a neutralization reaction, the acid donates protons (H⁺), which are accepted by the base (OH⁻) to form water
• Acids donate protons
• Neutralization reactions reduce the acidity and alkalinity of a solution.


  True
• What is one everyday application of neutralization reactions?

  Treating acid reflux
• Acid-Base reactions always produce hydrogen gas.

  False
• Neutralization reactions are important in treating acid reflux
• Match the acid and base with their neutralization products:

  HCl + NaOH ↔️ NaCl + H₂O

  CH₃COOH + NaOH ↔️ CH₃COONa + H₂O
• What type of ion does an acid donate in a neutralization reaction?

  Protons (H⁺)
• Steps in the neutralization reaction process

  1️⃣ Acid donates protons (H⁺)

  2️⃣ Base accepts protons (OH⁻)

  3️⃣ Water (H₂O) is formed

  4️⃣ Salt is formed
• Match the reactant type with an example:

  Acid ↔️ Hydrochloric acid (HCl)

  Base ↔️ Sodium hydroxide (NaOH)
• What are the two reactants in neutralization reactions?

  Acids and bases
• In a neutralization reaction, the base accepts protons (H⁺) to form water.

  True
• Match the reactant with its role in neutralization reactions:

  Acid ↔️ Donates protons (H⁺)

  Base ↔️ Accepts protons (H⁺)
• An acid-base neutralization reaction produces a salt and water.

  True
• Neutralization is the reaction between an acid and a base to form a salt and water
• Match the neutralization example with its products:

  HCl + NaOH ↔️ NaCl + H₂O

  CH₃COOH + NaOH ↔️ CH₃COONa + H₂O
• What are the two reactants in neutralization reactions?

  Acids and bases
• What two products are formed in a neutralization reaction?

  Salt and water
• Match the type of neutralization reaction with its correct description:

  Acid-Base ↔️ Salt and water

  Acid-Metal ↔️ Salt and hydrogen gas

  Acid-Carbonate ↔️ Salt, carbon dioxide, and water
• Order the reactants and products in an Acid-Base neutralization reaction:

  1️⃣ Acid (H⁺)

  2️⃣ Base (OH⁻)

  3️⃣ Salt

  4️⃣ Water
• In an Acid-Metal reaction, hydrogen gas is formed alongside a salt
