Statement I: On dehydration with P2O5 at 263 K, HCIO4 gives Cl2O7.
Statement II: This method is used in the preparation of Cl2O7.
To understand the given statements, let's first look at the reaction between HClO4 and P2O5.
HClO4 + P2O5 → Cl2O7 + H3PO4
This reaction shows that when HClO4 (perchloric acid) reacts with P2O5 (phosphorus pentoxide) at 263 K, it forms Cl2O7 (dichlorine heptoxide) and H3PO4 (phosphoric acid).
Now, let's analyze the given statements in detail:
Statement I: On dehydration with P2O5 at 263 K, HCIO4 gives Cl2O7.
This statement is correct. The reaction mentioned in Statement I is a known reaction in which HClO4 undergoes dehydration in the presence of P2O5 to form Cl2O7. Dehydration is the process of removing water or a molecule of water from a compound.
Statement II: This method is used in the preparation of Cl2O7.
This statement is also correct. The reaction between HClO4 and P2O5 is indeed used as a method to prepare Cl2O7. By dehydrating HClO4 with P2O5 at 263 K, Cl2O7 is formed.
Conclusion:
Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I. The reaction between HClO4 and P2O5 at 263 K results in the formation of Cl2O7, and this method is indeed used to prepare Cl2O7.
Therefore, the correct answer is option 'A' - Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.
Statement II: This method is used in the preparation of Cl2O7.
To understand the given statements, let's first look at the reaction between HClO4 and P2O5.
HClO4 + P2O5 → Cl2O7 + H3PO4
This reaction shows that when HClO4 (perchloric acid) reacts with P2O5 (phosphorus pentoxide) at 263 K, it forms Cl2O7 (dichlorine heptoxide) and H3PO4 (phosphoric acid).
Now, let's analyze the given statements in detail:
Statement I: On dehydration with P2O5 at 263 K, HCIO4 gives Cl2O7.
This statement is correct. The reaction mentioned in Statement I is a known reaction in which HClO4 undergoes dehydration in the presence of P2O5 to form Cl2O7. Dehydration is the process of removing water or a molecule of water from a compound.
Statement II: This method is used in the preparation of Cl2O7.
This statement is also correct. The reaction between HClO4 and P2O5 is indeed used as a method to prepare Cl2O7. By dehydrating HClO4 with P2O5 at 263 K, Cl2O7 is formed.
Conclusion:
Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I. The reaction between HClO4 and P2O5 at 263 K results in the formation of Cl2O7, and this method is indeed used to prepare Cl2O7.
Therefore, the correct answer is option 'A' - Both Statement I and Statement II are correct, and Statement II is the correct explanation of Statement I.
