(a)
Interpretation:
Interpret the reasons for the use of following step in the extraction of Argon gas from the liquid air.
The excess hydrogen is added into the mixture and then the mixture is ignited.
Concept introduction:
Fractional distillation is used to extract the Noble gas like Argon. Since the component gases of air have different boiling point therefore they separate at different temperatures but few gases which have almost same boiling point must be separate by different steps. For example argon and oxygen have same boiling point so oxygen must be removed with the help of different substances.
(b)
Interpretation:
Interpret the reasons for the use of following step in the extraction of Argon gas from the liquid air.
The mixture obtained in step 1 is passed over hot copper(III) oxide.
Concept introduction:
Fractional distillation is used to extract the Noble gas like Argon. Since the component gases of air have different boiling point therefore they separate at different temperatures but few gases which have almost same boiling point must be separate by different steps. For example argon and oxygen have same boiling point so oxygen must be removed with the help of different substances.
(c)
Interpretation:
Interpret the reasons for the use of following step in the extraction of Argon gas from the liquid air.
The mixture obtained in step 2 is passed over dehydrated zeolite material.
Concept introduction:
