Oxides of Sulphur - Two of the important oxides of sulphur are sulphur dioxide and sulphur trioxide. Sulphur dioxide is formed by burning sulphur in air or roasting metal sulphides in the presence of air. A large amount..

The catalysts used in this process are platinum or vanadium pentoxide (V 2 O 5 ) that are heated to a high temperature. The optimum temperature required is 450 - 500 o C. Remember:- Low temperature favours the oxidation of sulphur dioxide. If the temperature is too low, ..

Substances that can accept electrons, and thereby oxidize other substances, are called oxidizing agents. Non-metals ionize by accepting electrons. Hence, they are oxidizing agents. As they accept electrons, they get reduced. Oxygen, fluorine, chlorine, sulphur..

All the elements of this group have ns 2 np 4 configuration in their outermost shell. Therefore, the atoms of these elements try to gain or share two electrons to achieve noble gas configuration. Since oxygen has a very high value of electronegativity, it tends to achieve noble gas configuration pr..

It oxidizes sulphur dioxide to sulphur trioxide It oxidizes potassium ferrocyanide solution to potassium ferricyani..

Basic oxides are the oxides of metals. If soluble in water they react with water to produce hydroxides (alkalies) e.g., ..

Sulphur trioxide is formed by any of the following methods.: (i) Catalytic oxidation of sulphur dioxide (iii) Dehydration of H 2 SO 4 ..

Take some sulphur in a deflagrating spoon and heat it till it catches fire. Then introduce into a jar of oxygen. The sulphur will burn much more vigorously with a bluish flame, forming sulphur dioxide. Add some water into the jar and shake well. A test of this solutio..
