If a student says acids are always dangerous and bases are always safe, what is the correct response?
Answer and explanation
Correct answer: The statement is wrong because strong acids and strong bases can both be harmful
The governing concept is chemical safety, which depends on a substance’s nature, strength, concentration, and exposure rather than simply whether it is an acid or a base. Concentrated sulphuric acid can cause severe burns, while strong sodium hydroxide can also damage skin and tissues. Some dilute acids and bases are safe in controlled uses, but that does not make every one harmless. Therefore option A is correct; the absolute claims in B, C, and D are false.
