Why Na2S2O3.5H2O is known as Hypo?

Sodium Thiosulphate was originally called Hyposulphite of Soda and Hypo is simply the short form of this common name still in use. The origin of this term is uncertain. However, Hypo is the Greek word for 'under' and if you take a look at the structure of sodium hyposulphate you will note that the sulphite ion (SO3-2) is bonded to a sulphur atom ( as in replacing an oxygen atom of SO4-2 with a sulphur atom- thiosuphate). For purpose of symmetry, the structure of thiosulphate is drawn with the sulphur on top and the sulphite 'under' the sulphur. Hence the term hypo. Read more at related link.
