properties of rhombic sulphur

(i) It is a most stable and common form of sulphur. (ii) It is also called a -Sulphur. (iii) It has bright yellow colour. (iv) It is insoluble in water and carbon disulphide. (v) Its density is 2.07 g cm - 3 . (vi) It exists as S 8 molecule. The eight sulphur atoms..

The shapes of rhombic and monoclinic sulphur are different because of the difference in the packing of molecules. Those both contain S 8 rings and the molecules are stacked differently as shown in the figure abov..

A chemical element is said to exhibit allotropy when it occurs in two or more free forms in the same physical state; the forms are called allotropes. Allotropes generally differ in physical properties such as color and hardness; they may also differ in molecular structure or chemical act..

Chemical Properties of Sulphur - With Metals - With most of the metals the reaction of sulphur is highly exothermic. Sulphur combines with metals under varying conditions of temperature to form the respective sulphid..

Chemical Properties of Sulphuric Acid - As a Strong Acid - Sulphuric acid ionizes almost completely in water. Hence it acts as a strong acid. It also behaves as a strong electrolyte. Pure sulphuric acid is a weak electrolyte as it hardly has any water to form..
