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.

Therefore, the Correct Answer is C.

Q #1: Strong bases are:

A. Strong electrolytes

B. Weak electrolytes

C. Nonelectrolytes

D. Also strong acids

Answer Explanation

a. Strong electrolytes (Correct Answer): Strong bases completely dissociate into ions in solution, making them strong electrolytes. They conduct electricity well due to the presence of a high concentration of ions.

b. Weak electrolytes: Strong bases, unlike weak bases, completely dissociate in solution, resulting in a high concentration of ions. Therefore, they are considered strong electrolytes, not weak electrolytes.

c. Nonelectrolytes: Nonelectrolytes do not ionize in solution and do not conduct electricity. Strong bases, however, ionize completely in solution, making them strong electrolytes.

d. Also strong acids: Strong bases and strong acids are two distinct types of compounds. Strong bases ionize completely in solution to produce hydroxide ions, while strong acids ionize completely to produce hydrogen ions (H+). They are not the same.
Q #2: What is an appropriate pH value for hydrochloric acid?

A. pH 2-4

B. pH 1-3

C. pH 0-2

D. pH 3-5

Answer Explanation

Rationale for each choice:

A) pH 2-4: While hydrochloric acid is indeed highly acidic, a pH range of 2-4 would suggest a slightly less concentrated solution. However, this range might still be appropriate for dilute or partially neutralized hydrochloric acid.

A) pH 1-3 (Correct Answer): Hydrochloric acid typically has a very low pH due to its strong acidic nature. A pH range of 1-3 is commonly observed for concentrated hydrochloric acid solutions.

C) pH 0-2: This range suggests an even stronger acidity, which could be true for very concentrated hydrochloric acid solutions, although they might not commonly occur in typical laboratory or industrial settings.

D) pH 3-5: This pH range would indicate a significantly less acidic solution compared to hydrochloric acid. Such a pH range might be more appropriate for weak acids or diluted hydrochloric acid solutions rather than the concentrated form.
Q #3: 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.
