Importance of pollutants

 Definition:- Any unwanted and undesirable change in physical , chemical and biological characters of air ,water or land is called pollution .
:- As a result of pollution , human life, useful organisms , living conditions , environment ,raw materials etc . Are  irreparably damage and may even be destroyed permanently .
:- pollutants are substance , chemical or any other things which change the natural balance of environmental .
:- pollutants are mostly placed into two categories .
                1 . Biodegradable pollutants
            And
                2 .Non- biodegradable pollutants.

Biodegradable pollutants:- 
  Domestic sewage , cloth, paper , wood etc can be decomposed by bio microorganisms
that's why it is biodegradable pollutants .
Non- biodegradable pollutants:- 
  Aluminium cans, plastic , mercury compounds , DDT, glass etc are non- biodegradable materials .  These are nither
decomposed by microorganisms nor these materials breakdown by physical and chemical agents present in the environment.
Importance of pollutants :- 
:- Biodegradable pollutants provide energy in the form of organic substances and also nutrients like carbonate ,phos phosphate etc .
:- Non- biodegradable pollutants , not only accumulate in the ecosystem but pass from one organism of the food chain to another till it reaches the last tropic lavel .
:- During this transport , the amount of the pollutant continues to increase with each trophic level . This is called Bio magnification .

Siemens Ozoniser how Siemens Ozoniser work

Siemens Ozoniser:  This Ozoniser consist of two co-axial glass tubes fused together at one end. The outer side of the outer glass tube and the inner side of the inner glass tube are finally coated with tin foils as shown in the figure given below.  (Siemens Ozoniser)->2                                                     (Siemens Ozoniser)->1 These tin foil are connected  to the induction coil for supply of silent electric discharge. Pure and dry oxygen gas is passed into the apparatus through annular space. The gas is then subjected to the action of silent electric discharge where oxygen gets converted into ozone. The ozonised oxygen then comes out  of the apparatus through the outlet of the Ozoniser. (Siemens Ozoniser)->2

Rutile structure

-
Rutile structure: The radius radio is in the range 0.73 to 0.41. in rutile (TiO²) each Ti⁴+ ion is octahedrally surrounded by six O²- ions whereas each other O²- ion is surrounded by only three Ti⁴+ ions arranged at the tree corners of a plane triangle. The Co-ordination number of Ti⁴+ and O²+ ions are 6 and 3, respectively. It is not exactly a close packed structure. Ti⁴+ ions in rutile may however, be considered as forming a sufficiently distorted body centred cubic lattice.           Example  compounds  having radius ratio below 0.41 are SiO² and BeF² but these are only a few. The Co-ordination number of Si⁴+ and Be²+ is four and that of O²- is two. However, these are appreciably co-valent.

F - block element What are f - block elements

What are F - Block Elements - F - block elements are consist of Lanthanides and Actinides. In Lanthanides, they are 14 element immediately following Lanthanum (57) from cerium (58) to lutecium (71) . These 14 element are called Lanthanides . These Lanthanides belong to first inner transition series .           In Actinides , these are also 14 elements immediately following Actinium (89) starting from Thorium (90) to lawrencium (103) . The element from Th (90) to Lr (103) are called Actinides . They belong to second inner transition series.
