Question

some uses of organic and inorganic acids 

Answer 1

organic: In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such as formic and lactic acids are miscible in water, but higher molecular mass organic acids, such as benzoic acid, are insoluble in molecular (neutral) form.On the other hand, most organic acids are very soluble in organic solvents. p-Toluenesulfonic acid is a comparatively strong acid used in organic chemistry often because it is able to dissolve in the organic reaction solvent.Exceptions to these solubility characteristics exist in the presence of other substituents that affect the polarity of the compound 
inorganic :-Commonly used mineral acids are sulfuric acid, hydrochloric acid and nitric acid (They are also known as bench acids). Mineral acids range from acids of great strength (example: sulfuric acid) to very weak (boric acid). Mineral acids tend to be very soluble in water and insoluble in organic solvents.Mineral acids are used in many sectors of the chemical industry as feedstocks for the synthesis of other chemicals, both organic and inorganic. Large quantities of these acids – especially sulfuric acid, nitric acid, and hydrochloric acid – are manufactured for commercial use in large plants.Mineral acids are also used directly for their corrosive properties. For example, a dilute solution of hydrochloric acid is used for removing the deposits from the inside of boilers, with precautions taken to prevent the corrosion of the boiler by the acid. This process is known as descaling.

Answer 2

INORGANIC NITROGEN: Inorganic soil nitrogen includes ammonium (NH4+), nitrite (NO2-), nitrate (NO3-), nitrous oxide (N2O), nitric oxide (NO), and elemental nitrogen (N2), which is inert except for its utilization by Rhizobia and other Nitrogen fixing microorganisms, for plants, NH4+), (NO2-), and (NO3-) are the most important and are produced from aerobic decomposition for soil on or from addition of nitrogen fertilizers. These forms represents 2 to 5% of total soil nitrogen (N2O-), and no are important nitrogen forms lost through denitrification. Organic Nitrogen: Organic soil nitrogen occurs as proteins, amino acids, amins sugars, and other complex nitrogen compounds. the proportion of total soil nitrogen in these various fractions is : bound amino acids, 20 to 40%; amino sugars such as the hexosoning 5 to 10%; and purine and pyrimidine derivatives, 1% very little is known about the chemical nature of the 50% or so of the organic nitrogen not found in these fractions. proteins are commonly found in combination with clays, lignin, and other materials resistant decompostion the biological oxidation of free amino acids is an important source of (NH4+),  relative its other forms, the quantities of free amino acids in soils are low.
