In the heart of the arid landscape, the sun blazes unforgivingly across vast expanses of cracked earth and shimmering dunes. Sparse vegetation clings tenaciously to life, with hardy cacti and thorny shrubs defying the relentless drought. Winds whisper through the desolation, carrying fine dust that paints the horizon in muted tones of gold and gray, where only the most resilient creatures—lizards skittering over hot sands and eagles soaring above—endure the unyielding embrace of aridity.

1. Question: What is the definition of an acid according to the Arrhenius theory?
Options:
A) A substance that donates protons (H⁺ ions)
B) A substance that accepts protons (H⁺ ions)
C) A substance that produces hydroxide ions (OH⁻) in water
D) A substance that increases the pH of a solution
Answer: A) A substance that donates protons (H⁺ ions)
Explanation: The Arrhenius theory defines an acid as a substance that increases the concentration of H⁺ ions when dissolved in water.
2. Question: Which of the following is a strong acid?
Options:
A) Acetic acid
B) Hydrochloric acid
C) Carbonic acid
D) Phosphoric acid
Answer: B) Hydrochloric acid
Explanation: Hydrochloric acid (HCl) is a strong acid because it completely dissociates in water, unlike weak acids such as acetic acid.
3. Question: What is the pH value of a neutral solution?
Options:
A) Less than 7
B) Exactly 7
C) Greater than 7
D) Between 0 and 14
Answer: B) Exactly 7
Explanation: A neutral solution has a pH of 7, indicating an equal concentration of H⁺ and OH⁻ ions.
4. Question: Which acid is commonly found in citrus fruits?
Options:
A) Lactic acid
B) Citric acid
C) Sulfuric acid
D) Nitric acid
Answer: B) Citric acid
Explanation: Citric acid is a weak organic acid present in lemons, oranges, and other citrus fruits, giving them their sour taste.
5. Question: What happens when an acid reacts with a base?
Options:
A) Neutralization reaction
B) Oxidation reaction
C) Reduction reaction
D) Precipitation reaction
Answer: A) Neutralization reaction
Explanation: Acids and bases react to form salt and water in a neutralization reaction, balancing the pH.
6. Question: Which of the following is not a property of acids?
Options:
A) They turn blue litmus paper red
B) They have a sour taste
C) They feel slippery
D) They react with metals to produce hydrogen gas
Answer: C) They feel slippery
Explanation: Slippery feel is a property of bases, not acids; acids typically have a sour taste and turn blue litmus red.
7. Question: What is the chemical formula for sulfuric acid?
Options:
A) HNO₃
B) HCl
C) H₂SO₄
D) CH₃COOH
Answer: C) H₂SO₄
Explanation: Sulfuric acid is represented by the formula H₂SO₄ and is widely used in industrial applications.
8. Question: In the pH scale, what does a pH of 2 indicate?
Options:
A) A strong base
B) A weak acid
C) A strong acid
D) A neutral solution
Answer: C) A strong acid
Explanation: A pH of 2 indicates a very acidic solution, as lower pH values correspond to higher concentrations of H⁺ ions in strong acids.
9. Question: Which acid is used in car batteries?
Options:
A) Hydrochloric acid
B) Sulfuric acid
C) Acetic acid
D) Nitric acid
Answer: B) Sulfuric acid
Explanation: Sulfuric acid is the electrolyte in lead-acid car batteries, facilitating the chemical reactions for energy storage.
10. Question: What is the conjugate base of hydrochloric acid (HCl)?
Options:
A) Cl⁻
B) H₂O
C) OH⁻
D) H₃O⁺
Answer: A) Cl⁻
Explanation: The conjugate base of HCl is Cl⁻, formed when HCl donates its proton (H⁺).
11. Question: Which of the following acids is monoprotic?
Options:
A) Sulfuric acid
B) Phosphoric acid
C) Hydrochloric acid
D) Carbonic acid
Answer: C) Hydrochloric acid
Explanation: Hydrochloric acid (HCl) is monoprotic because it can donate only one proton per molecule.
12. Question: What is the effect of dilution on the pH of an acid?
Options:
A) pH decreases
B) pH increases
C) pH remains the same
D) pH becomes zero
Answer: B) pH increases
Explanation: Diluting an acid with water decreases the concentration of H⁺ ions, which increases the pH value.
13. Question: Which acid is produced during the fermentation of milk?
Options:
A) Lactic acid
B) Citric acid
C) Acetic acid
D) Formic acid
Answer: A) Lactic acid
Explanation: Lactic acid is produced by bacteria during the fermentation process that turns milk into yogurt or curd.
14. Question: What is the role of acids in the stomach?
Options:
A) To neutralize food
B) To aid in digestion
C) To increase pH
D) To produce energy
Answer: B) To aid in digestion
Explanation: Hydrochloric acid in the stomach helps break down food and kill bacteria, facilitating digestion.

Options:
A) Nitric acid
B) Acetic acid
C) Perchloric acid
D) Hydrobromic acid
Answer: B) Acetic acid
Explanation: Acetic acid (CH₃COOH) is a weak acid because it only partially dissociates in water.
16. Question: What gas is produced when an acid reacts with a metal carbonate?
Options:
A) Hydrogen gas
B) Carbon dioxide gas
C) Oxygen gas
D) Nitrogen gas
Answer: B) Carbon dioxide gas
