Which acid is needed to make ammonium nitrate?

A. Sulfuric acid

B. Hydrochloric acid

C. Nitric acid

D. Acetic acid

Answer Explanation:

A) Sulfuric acid: Sulfuric acid is not used in the production of ammonium nitrate. Although sulfuric acid is a widely used acid in various industries, it is not involved in the synthesis of ammonium nitrate.

B) Hydrochloric acid: Hydrochloric acid is not used in the production of ammonium nitrate. While it is an important industrial acid, it does not react with ammonia to produce ammonium nitrate.

C) Nitric acid (Correct Answer): Ammonium nitrate is typically produced by reacting ammonia (NH3) with nitric acid (HNO3). The reaction forms ammonium nitrate (NH4NO3), which is a common fertilizer and explosive compound.

D) Acetic acid: Acetic acid, commonly known as vinegar, is not used in the production of ammonium nitrate. It is a weak acid and does not react with ammonia to form ammonium nitrate.

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: Why is KOH a strong alkali?

A. Because it reacts vigorously with acids

B. Because it forms a basic solution when dissolved in water

C. Because in solution it fully dissociates into K+ and OH-

D. Because it forms insoluble precipitates with metal cations

Answer Explanation

A) Because it reacts vigorously with acids: While KOH does react with acids to form salts and water, the strength of an alkali is not solely determined by its reactivity with acids.

B) Because it forms a basic solution when dissolved in water: This statement is true, but it does not fully explain why KOH is considered a strong alkali. Many compounds can form basic solutions when dissolved in water.

C) Because in solution it fully dissociates into K+ and OH- (Correct Answer): KOH is considered a strong alkali because it fully dissociates in aqueous solution into potassium ions (K+) and hydroxide ions (OH-). This dissociation leads to a high concentration of hydroxide ions in solution, making it strongly alkaline.

D) Because it forms insoluble precipitates with metal cations: This statement describes the formation of insoluble hydroxide precipitates when alkali solutions are added to solutions of metal salts. However, it does not fully explain why KOH itself is considered a strong alkali.
Q #3: Which type of solution is one with a pH of 8?:

A. Acidic

B. Basic

C. Neutral

D. Pure

Answer Explanation

a. Acidic: Solutions with pH values below 7 are considered acidic. A pH of 8 indicates a solution that is more basic than acidic.

b. Basic (Correct Answer): Solutions with pH values above 7 are considered basic or alkaline. A pH of 8 indicates a basic solution.

c. Neutral: Solutions with a pH of 7 are considered neutral. A pH of 8 indicates a solution that is slightly basic, not neutral.
