Dilute A:
- i. has no oxidizing property
- ii. reacts with Cu
- iii. has no dehydrating property
Think it through first, then pick an option.
- a i and ii
- b ii and iii
- c i and iii
- d i, ii and iii
Answer and explanation
Correct answer: c i and iii
Dilute H₂SO₄ has neither the oxidizing nor the dehydrating property; both belong to the concentrated acid.
Why the other options are wrong
- a i and ii: ii is false: it is concentrated H₂SO₄ that oxidizes copper, not the dilute acid.
- b ii and iii: ii is false: dilute H₂SO₄ has no oxidizing property, so it does not react with Cu; and i is left out.
- d i, ii and iii: ii is false: reacting with Cu is a property of concentrated H₂SO₄.
