Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R): Assertion (A): Helium is used to dilute oxygen in the diving apparatus. Reason (R): Helium has a high solubility in . In light of the above statements, choose the correct answer from the options given below:
(A) is False but (R) is True.
Both (A) and (R) are True and (R) is the correct explanation of (A).
Both (A) and (R) are True and (R) is not the correct explanation of (A).
(A) is True but (R) is False.
Assertion (A) is true because the tanks used by scuba divers are filled with air diluted with helium (11.7% helium, 56.2% nitrogen and 32.1% oxygen) to avoid bends and the toxic effects of high concentrations of dissolved nitrogen in the blood underwater . Reason (R) is false because helium is chosen specifically because of its low solubility in blood, not high solubility in .
