Given below are two statements : one is labelled as Assertion \(A\) and the other is labelled as Reason \(F\) Assertion \(A\): Helium is used to dilute oxygen in diving apparatus. Reason \(R:\) Helium has high solubility in \(O _2\). In the light of the above statements, choose the correct answer from the options given below
- A \(A\) is false but \(R\) is true
- B Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)
- C Both \(A\) and \(R\) are true and \(R\) is NOT the correct explanation of \(A\)
- D \(A\) is true but \(R\) is false
Answer & Solution
Correct Answer
(D) \(A\) is true but \(R\) is false
Step-by-step Solution
Detailed explanation
Helium is used as diluent for oxygen in modern diving apparatus because of its very low solubility in blood. Gases diffuses easily with each other.
