Assertion and Reasoning
Assertion(A): For calculating AS2-, S3-, Al3+ ions are better than Na+ ions.
Reason(R): Size of Al3+ is smaller than Na.
Explanation:
The Assertion(A) states that calculating AS2-, S3-, Al3+ ions is better than Na+ ions.
The Reason(R) states that the size of Al3+ is smaller than Na.
Both Assertion and Reason are true but Reason is not the correct explanation of assertion.
The size of the ions is significant in determining the strengths of their respective acids.
The smaller the size of the ion, the stronger the acid.
Al3+ ions are smaller in size than Na+ ions, so Al3+ is a stronger acid than Na+.
Therefore, it is not correct to say that the size of Al3+ is the reason why it is better to calculate AS2-, S3-, Al3+ ions than Na+ ions.
Instead, the reason is that Al3+ is a stronger acid than Na+.
Conclusion:
Hence, the correct answer is option B.

The assertion states that for coagulating AS2, S3, and Al3+ ions, aluminum ions (Al3+) are better than sodium ions (Na+).
The reason given is that the size of Al3+ is smaller than Na+.
While both the assertion and reason are true, the reason provided does not directly explain why Al3+ ions are better for coagulation. The size difference between Al3+ and Na+ ions is not the sole determining factor for their effectiveness in coagulation.
The coagulation process involves various factors such as charge, valency, and the ability to form complexes with other species. In the case of Al3+ ions, their higher charge and smaller size make them more effective for coagulation processes compared to Na+ ions.
Therefore, while the size of Al3+ ions is smaller than Na+ ions (which is true), it is not the direct reason why Al3+ ions are better for coagulation (hence, the reason is not the correct explanation of the assertion).
