Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : In expensive scientific instruments, silica gel is kept in watch-glasses or in semipermeable membrane bags.
Reason (R) : Silica gel adsorbs moisture from air via adsorption, thus protects the instrument from water corrosion (rusting) and / or prevents malfunctioning.
In the light of the above statements, choose the correct answer from the options given below :
Multiple Choice Options
- A Both (A) and (R) are true and (R) is the correct explanation of (A)
- B (A) is true but (R) is false
- C (A) is false but (R) is true
- D Both (A) and (R) are true but (R) is not the correct explanation of (A)
Step-by-Step Verified Solution
Assertion is correct and Reason is correct explanation of Assertion.
Silica gel adsorbs moisture and thus products the instrument from water corrosion (rusting) and prevents malfunctioning.
