What do bases react with?

A. Acids to produce salts and water

B. Salts to produce acids and water

C. Water to produce acids and salts

D. Neither acids, salts, nor water

Answer Explanation:

A) Acids to produce salts and water (Correct Answer): Bases react with acids to form salts and water. This reaction is a common characteristic of bases, where they accept protons (H+) from acids to form water and salts.

B) Salts to produce acids and water: Bases typically do not react with salts to produce acids and water. The reaction between a base and a salt is not a common reaction in chemistry.

C) Water to produce acids and salts: Bases do not react with water to produce acids and salts. Bases can ionize in water to produce hydroxide ions (OH-) but do not typically react with water to produce acids and salts.

D) Neither acids, salts, nor water: Bases do react with acids to form salts and water, making choice D incorrect. Bases do not react with salts or water to produce acids, salts, or water.

Therefore, the Correct Answer is A.

Q #1: What is produced when an acid reacts with a metal carbonate or metal hydrogen carbonate?

A. Salt and water

B. Carbon dioxide and water

C. Oxygen gas and water

D. Salt and hydrogen gas

Answer Explanation

A) Salt and water: This reaction occurs when an acid reacts with a metal hydroxide or a metal oxide, not with a metal carbonate or metal hydrogen carbonate.

B) Carbon dioxide and water (Correct Answer): When an acid reacts with a metal carbonate or metal hydrogen carbonate, carbon dioxide gas is produced along with water and a salt. The carbonates decompose into carbon dioxide gas, water, and a salt when reacting with acids.

C) Oxygen gas and water: This reaction is not typical when an acid reacts with a metal carbonate or metal hydrogen carbonate. Metal carbonates and metal hydrogen carbonates generally do not produce oxygen gas when reacting with acids.

D) Salt and hydrogen gas: This reaction occurs when an acid reacts with a metal, not with a metal carbonate or metal hydrogen carbonate. When metals react with acids, hydrogen gas is typically produced along with a salt.
Q #2: What is produced when an acid reacts with a metal oxide?

A. Salt and water

B. Carbon dioxide and water

C. Oxygen gas and water

D. Hydrogen gas and water

Answer Explanation

A) Salt and water (Correct Answer): When an acid reacts with a metal oxide, a salt and water are typically produced. The metal in the metal oxide combines with the acid to form a salt, and water is produced as a byproduct of the reaction.

B) Carbon dioxide and water: This reaction occurs when an acid reacts with a metal carbonate, not a metal oxide. When carbonates react with acids, carbon dioxide gas is produced along with water and a salt.

C) Oxygen gas and water: This reaction is not typical when an acid reacts with a metal oxide. Metal oxides generally do not produce oxygen gas when reacting with acids.

D) Hydrogen gas and water: This reaction occurs when an acid reacts with a metal, not a metal oxide. When metals react with acids, hydrogen gas is typically produced along with water and a salt.
Q #3: What type of reaction occurs between sulfuric acid and ammonia?

A. Oxidation

B. Reduction

C. Neutralization

D. Precipitation

Answer Explanation

A) Oxidation: Sulfuric acid and ammonia do not participate in an oxidation-reduction reaction, where one substance loses electrons (oxidation) and another gains electrons (reduction).

B) Reduction: Sulfuric acid and ammonia do not participate in an oxidation-reduction reaction, so reduction is not the correct type of reaction.

C) Neutralization (Correct Answer): When sulfuric acid reacts with ammonia, a neutralization reaction occurs. The acidic hydrogen ions (H+) from sulfuric acid react with the basic ammonia molecules (NH3) to form ammonium ions (NH4+) and sulfate ions (SO4^2-), resulting in the formation of an ammonium sulfate salt.

D) Precipitation: A precipitation reaction occurs when two solutions react to form an insoluble solid (precipitate). However, sulfuric acid and ammonia do not form an insoluble product when they react. Therefore, precipitation is not the correct type of reaction for this scenario.
