What does it mean when a substance is described as acidic?

Highly soluble
Alkaline
Neutral
pH less than 7

The correct answer is: pH less than 7

When a substance is described as acidic, it means that it has a pH of less than 7. This indicates that the substance has a high concentration of hydrogen ions, making it more reactive and potentially corrosive. Options A, B, and C are incorrect because they do not accurately describe the property of acidity. Option A refers to solubility, which can apply to both acidic and basic substances. Option B refers to alkaline substances, which have a pH greater than 7 and are opposite to acidic substances. Option C refers to neutrality, in which the pH is exactly 7 and the substance is neither acidic nor basic. Therefore, the best answer is D.
