In the isolation of fluorine a number of difficulties were encountered.Which statements are incorrect :
Fluorine has great affinity for hydrogen
Fluorine reacts with moist glass vessels
Electrolysis of aqueous HF gives ozonized oxygen
The potential required for the discharge of the fluoride ions lowest

Question

In the isolation of fluorine a number of difficulties were encountered.Which statements are incorrect :
Fluorine has great affinity for hydrogen
Fluorine reacts with moist glass vessels
Electrolysis of aqueous HF gives ozonized oxygen
The potential required for the discharge of the fluoride ions lowest

Toppr Admin · Accepted Answer

A- Fluorine reacts with water and glass vessels-Thus- option A is incorrect-B- Fluorine has great affinity for hydrogen- It reacts with hydrogen with an explosion even in dark-However- this was not the difficulty encountered in the extraction of fluorine-Thus- option B is incorrect-C- The electrolysis of aqueous HF gives oxygen and not ozonized oxygen-Thus- option C is also incorrect-D- The potential required for the discharge of the fluoride ions is lowest-Thus- option D is also correct-
