Answer 2

Answer:

The compound sodium thiosulphate is generally used in photography as a fixer because of its complex forming behaviour.

Explanation:

Since sodium thiosulfate has a complex forming ability, during photography, it reacts with the undecomposed silver bromide( AgBr) to form a silver thiosulphate complex which is soluble in nature.

It is mainly used as a photographic fixer used for both film as well as photographic paper processing methods.
