Which of the following two combinations are correct?
| Metal | Gas Evolved | |
| (i) | Copper | Yes |
| (ii) | Iron | Yes |
| (iii) | Magnesium | No |
| (iv) | Zinc | Yes |
(A) i and iii
(B) i and iv
(C) ii and iii
(D) ii and iv
Answer
This is the reaction of Metal with Acid -
Most metals react with Acids, to evolve gas. But some metals are too unreactive.
From our options
- Copper does not react with Acids
- Iron reacts with Acids to liberate Hydrogen gas
- Magnesium reacts with Acids to liberate Hydrogen gas
-
Zinc
reacts with Acids to liberate Hydrogen gas
Thus, options (ii) and (iv) are correct.
So, the correct answer is (d)
