Crystalline and Non-Crystalline Varieties of Sulfur: Crystalline Varieties of Sulfur: Rhombic Sulfur: This is also called octahedral sulfur. It is a stable form of sulfur. Preparation: Some flowers of sulfur are dissolved in carbon disulfide taken in a china dish. The resulting solution is filtered rapidly. The filtrate is allowed to evaporate slowly in the open air. Octahedral crystals of rhombic sulfur are obtained. Properties of Rhombic Sulfur: It is the only form of sulfur which is stable at below 95.6°C. It is soluble in organic solvents like benzene, carbon disulfide but is insoluble in water. Its specific gravity is … Continue reading Crystalline and Non-Crystalline Varieties of Sulfur
