Question

green vitriol is homogenous mixture or heterogeneous mixture​

Answer 1

Answer:

These materials were originally found as crystals formed by evaporation of groundwater that percolated through sulfide minerals and collected in pools on the floor of old mines. The word vitriol comes from the Latin word vitriolus, meaning "small glass", as those crystals resembled pieces of colored glass.

Oil of vitriol was an old name for concentrated sulfuric acid, which was obtained by the alchemist Jabir ibn Hayyan (c. 721–815 CE) through the dry distillation (pyrolysis) of vitriols. The name, shortened to vitriol, continued to be used for this viscous liquid long after the minerals came to be called "sulfates". The term vitriolic in the sense of "harshly condemnatory" is derived from the corrosive nature of this substance.
