An Approach towards the Determination of Alkalinity in Water, Its Experimental Consideration & Comparison with Traditional Method: An Overview
Abstract
Alkalinity is equal to the stoichiometric sum of the bases in solution therefore it includes all the acid neutralizing bases in water namely OHˉ, CO3²ˉ & HCO3ˉ ions. In the natural environment carbonate alkalinity tends to make up most of the total alkalinity due to the common occurrence and dissolution of carbonate rocks and presence of CO2 in the atmosphere. Alkalinity varies with the location Acid-base titration is performed for their estimation but the theoretical determination for the type and extent of these ions is tedious process through traditional formulas known to us, (Volume of acid used up till Phenolphthalein & Methyl orange end point). Here in this paper we are trying to simplify the method and reporting the direct determination of the extent of ions by simple calculation without using the formulas for specific ions under different conditions of alkalinity. Thus a comparative aspect of this approach with traditional method will be covered by us in this paper.
