Match List-I with List-II and select the correct answer using the code given below the Lists :
List-I
(Trade Name)List-II
(Chemical Name)A. Bleaching powder 1. Sodium bicarbonate B. Baking soda 2. Sodium carbonate, 10 water C. Washing soda 3. Calcium oxychloride D. Plaster of Paris 4. Calcium sulphate, \(\frac{1}{2}\) water
Code:
A B C D
This question requires matching chemical compounds, identified by their common trade names in List-I, with their correct chemical names provided in List-II. Understanding these common names and their corresponding chemical formulas is crucial in chemistry.
List-I contains common trade names for various chemical substances, while List-II provides their corresponding chemical names and formulas.
| List-I (Trade Name) |
| A. Bleaching powder |
| B. Baking soda |
| C. Washing soda |
| D. Plaster of Paris |
| List-II (Chemical Name) |
| 1. Sodium bicarbonate |
| 2. Sodium carbonate, 10 water |
| 3. Calcium oxychloride |
| 4. Calcium sulphate, 1/2 water |
Let's examine each trade name from List-I and find its corresponding chemical name from List-II:
The trade name Bleaching powder refers to Calcium oxychloride. Its chemical formula is typically represented as \(\text{Ca}(\text{OCl})_2\). This corresponds to item 3 in List-II.
The common name Baking soda is the widely used name for Sodium bicarbonate. Its chemical formula is \(\text{NaHCO}_3\). This matches item 1 in List-II.
Washing soda is the trade name for Sodium carbonate decahydrate. The name "Sodium carbonate, 10 water" accurately describes this hydrated salt, with the formula \(\text{Na}_2\text{CO}_3 \cdot 10\text{H}_2\text{O}\). This corresponds to item 2 in List-II.
Plaster of Paris is the common name for Calcium sulphate hemihydrate. The description "Calcium sulphate, 1/2 water" refers to its chemical composition, represented by the formula \(\text{CaSO}_4 \cdot \frac{1}{2}\text{H}_2\text{O}\). This matches item 4 in List-II.
Based on the detailed matching:
Therefore, the correct sequence for A B C D is 3 1 2 4.
