Correct Answers: ✅ C. HI ✅ D. HCl

Rationale:

Acids are substances that donate hydrogen ions (H⁺) in a solution.
- HI (Hydroiodic acid) and HCl (Hydrochloric acid) are both strong acids because they fully dissociate in water, releasing H⁺ ions.
- Acids typically have a pH below 7 and contribute to an increase in H⁺ concentration.

Why the Other Choices Are Incorrect:

A. NaOH ❌
- Sodium hydroxide (NaOH) is a strong base, not an acid. It accepts H⁺ ions and increases hydroxide (OH⁻) concentration.
B. KOH ❌
- Potassium hydroxide (KOH) is also a strong base, functioning like NaOH by neutralizing acids.

Final Answer: ✅ C. HI ✅ D. HCl

35:T545,

Correct Answer: ✅ D. < 7

Rationale:

Acids have a pH below 7 because they contain hydrogen ions (H⁺), which make them acidic. The pH of these substances falls within the acidic range:
- Hydrochloric acid (HCl): Strong acid with a pH around 1 in pure form, commonly found in the stomach.
- Orange juice: Contains citric acid, giving it a pH of around 3-4.
- Coffee: Slightly acidic, with a pH around 4-5, depending on the roast and brewing method.

Why the Other Choices Are Incorrect:

A. Between 7 and 10 ❌
- This range includes neutral (7) and basic (>7) substances, but acids are below 7.
B. Between 0 and 10 ❌
- While acids can be between 0 and 7, this option includes basic substances (above 7), making it incorrect.
C. > 7 ❌
- A pH greater than 7 indicates bases, not acids.

Final Answer: ✅ D. < 7
