Question

what were the difficulties in the preparation of fluorine ? explain how the difficulties were overcome

Answer 1

The difficulties in the preparation of fluorine are as follows:-

• Fluorine is not available in free state because it has an extreme reactivity.
• Oxidization is not possible in fluorine.
• Preparation is not possible by the electrolysis of hf.

• It is very difficult to separate fluorine from its compounds.

There are two ways which scientist adopted in order to prepare fluorine.

1. Dennis method.
2. Whytlaw Gray's method.

Answer 2

Explanation:

Difficulties to isolate the fluorine as follows:

• It is most electronegative element.
• Oxidation is not possible for this element
• It exist as F-  form in the metals
• Fluorine is a very strong oxidizing element.
• It cannot be prepared by the electrolysis process.
• Fluorine molecule is extremely reactive.
• If we separate the fluorine during the electrolysis it is reacted with graphite which is used as an electrode..

• We cannot store the fluorine gas because it is extremely reactive.
• The following methods are used to prepare fluorine. They are Dennis method and Whytlaw Gray's method .
