The reagent used to remove the traces of oxygen from a mixture of noble gases is:
Open in App
Solution
The correct option is B alkaline pyrogallol solution
Pyrogallol is the common name of 1,2,3-trihydroxybenzene.
Hydroxy groups are strong activavtors of aromatic ring . when the time 3 hydroxyl groups have been added to
a benzene nucleus we will have have a
very reactive molecule, reactive enough to react with oxygen in the noble gases
in air.
Hence option C Is correct.
