Chemistry - Hydrogen and Its compound Question with Solution | TestHub
Match the Product listed in Column-I to the corresponding Reaction(s) mentioned in Column-II :
List - I (Product formed) | List - II (Type of reaction) |
|---|---|
(1) | (P) electrolysis of |
(2) | (Q) prolonged electrolysis of water ( ) |
(3) ( ) | (R) water gas shift reaction |
(4) | (S) auto oxidation of 2 ethyl anthraquinol |
| (T) silent electric discharge of oxygen gas |
Options:
Answer:
Solution:
(1) D₂O is concentrated and obtained by the prolonged electrolysis of ordinary water (Q) because H₂O is electrolyzed more readily than heavy water.
(2) H₂O₂ is industrially manufactured by both the electrolysis of 50% H₂SO₄ (P) and the auto-oxidation of 2-ethylanthraquinol (S).
(3) H₂ + CO₂ are the specific products obtained when water gas (CO + H₂) undergoes the water gas shift reaction (R) with steam.
(4) O₃ (Ozone) is formed by subjecting pure, dry oxygen gas to a silent electric discharge (T) to prevent its decomposition .
