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: What color do acids make litmus paper turn?

    A. Red

    B. Yellow

    C. Blue

    D. Black

    Answer Explanation

    A) Red (Correct Answer): Acids turn litmus paper red. Litmus paper is a common indicator that changes color in response to changes in acidity or alkalinity. Acids change the blue litmus paper to red.

    B) Yellow: Acids do not typically turn litmus paper yellow. Litmus paper is generally unaffected by acids in a way that would cause it to turn yellow.

    C) Blue: Acids do not turn litmus paper blue. Instead, they change blue litmus paper to red.

    D) Black: Acids do not turn litmus paper black. Litmus paper is not expected to change to black in the presence of acids.

  • Q #2: :pH is a measure of how acidic or basic a substance is. The pH scale ranges from:

    A. 0–7

    B. 7–14

    C. 0–14

    D. 1–10

    Answer Explanation

    A. 0–7: This range corresponds to acidic solutions on the pH scale. A pH value below 7 indicates acidity.

    B. 7–14: This range corresponds to basic solutions on the pH scale. A pH value above 7 indicates alkalinity.

    C. 0–14 (Correct Answer): The pH scale ranges from 0 to 14, covering the entire spectrum of acidity and alkalinity. A pH value of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity.

    D. 1–10: This range does not encompass the full range of the pH scale. The pH scale extends beyond 10 for alkaline solutions and below 1 for highly acidic solutions. Therefore, this choice is incorrect.

  • Q #3: 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.
