Ash


Ash or ashes are the solid remnants of fires. Specifically, it refers to all non-aqueous, non-gaseous residues that remain after something is burned. In analytical chemistry, in order to analyse the mineral and metal content of chemical samples, ash is the non-gaseous, non-liquid residue after a complete combustion.
Ashes as the end product of incomplete combustion will be mostly mineral, but usually still contain an amount of combustible organic or other oxidizable residues. The best-known type of ash is wood ash, as a product of wood combustion in campfires, fireplaces, etc. The darker the wood ashes, the higher the content of remaining charcoal will be due to incomplete combustion. The ashes are of different types.Some ashes which have natural compound makes soil fertile. But some which have chemical compound can make it toxic. but in some cases they are broken up by soil and microorganisms.
Like soap, ash is also a disinfecting agent. The World Health Organization recommends ash or sand as alternative when soap is not available.

Natural occurrence

Natural occurrence the natural occurrence mostly depends upon fire,and effects mainly on natural vegetation. The main agents are Lightning volcanic activities and other activities after the vegetation is dead the ashes maybe submerged in soil to make it fertile or may be get deepened under the soil for long period of time, And this can result to carbonisation and convert them in to coal. The ashes are of different types.Some ashes which have natural compound makes soil fertile. But some which have chemical compound can makes its toxic.
