The correct Answer is:
To solve the problem, we need to analyze the two statements provided regarding cupric and cuprous metaborate. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The statement claims that "Colourless cupric metaborate is reduced to cuprous metaborate in a luminous flame." - Cupric metaborate is typically blue in color, not colorless. The reduction process involves converting cupric (Cu^2+) to cuprous (Cu^+), which indeed occurs in a luminous flame, but the initial compound is incorrectly described as colorless. 2. **Conclusion for Statement 1**: - Since cupric metaborate is blue, the statement is false. The correct reaction would be the reduction of blue cupric metaborate to colorless cuprous metaborate. 3. **Understanding Statement 2**: - The statement claims that "Cuprous metaborate is obtained by heating boric anhydride and copper sulfate in a non-luminous flame." - When we heat boric anhydride (B2O3) and copper sulfate (CuSO4), the expected product is cupric metaborate (CuBO2) and sulfur trioxide (SO3), not cuprous metaborate. 4. **Conclusion for Statement 2**: - The statement is also false because the reaction yields cupric metaborate, not cuprous metaborate. 5. **Final Conclusion**: - Both statements are false. Therefore, the most appropriate answer is that both statements are incorrect. ### Final Answer: Both Statement 1 and Statement 2 are false. ---
