Why is sulphuric acid known as king of chemicals and oil vitriol ?
उत्तर
Sulphuric acid is known as king of chemicals because in almost all industries it is used directly or indirectly.
In 8th century it was obtained by distillation of green vitriol (FeSO4.7H2O). It is called oil of green vitriol because of its oily appearance and because of the fact that it was present in vitreous or glassy substances like ferrous sulphate etc.
