Assertion (A): Usually the sulphide ore is converted to oxide before ...
Assertion (A): Usually the sulphide ore is converted to oxide before reduction.
Reason (R): Reduction of oxides occurs easier.
Explanation:
The correct answer is option 'A', which states that both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Reasoning behind the answer:
1. Conversion of Sulphide Ore to Oxide:
- Sulphide ores are usually converted to oxides before the reduction process.
- This conversion is done through a process called roasting or calcination.
- Roasting is a process in which the sulphide ore is heated strongly in the presence of excess air.
- During roasting, the sulphide ore reacts with oxygen in the air to form metal oxide and sulphur dioxide gas.
- The reaction can be represented as follows:
Sulphide Ore (s) + Oxygen (g) → Metal Oxide (s) + Sulphur Dioxide (g)
2. Reason for Conversion to Oxide:
- The reason behind converting sulphide ore to oxide is that reduction of oxides occurs easier than reduction of sulphides.
- Reduction is a process in which metal oxides are reduced to their respective metals.
- Reduction of metal oxides is easier because oxides have a higher oxygen content and are more reactive compared to sulphides.
- During reduction, oxygen is removed from the metal oxide, resulting in the formation of metal.
- The reduction of metal oxides can be achieved through various methods like heating with carbon or using other reducing agents.
Conclusion:
- The assertion (A) that sulphide ore is converted to oxide before reduction is true.
- The reason (R) that reduction of oxides occurs easier is also true and provides a correct explanation for the assertion.
- Therefore, option 'A' is the correct answer.
