Abstract:
The analysis of rain water samples were carried out in the Department of Soil Science and Agricultural Chemistry Laboratory at the Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2015. The rain water samples of two different location viz. Lanka and Mirzamurad (Banaras Hindu University, campus), which are relatively free from industrial pollution were examined during south-west monsoon period (July to September) in Varanasi using standardize collection and analytical techniques for evaluation chemical composition of rain water. Magnesium was found in highest amount in comparison to other cations, followed by Ca²⁺, Na⁺, K⁺ and NH₄⁺. Thus, the order of alkali metal cations found in rain water in Varanasi was as follows: Mg²⁺>Ca²⁺>Na⁺>K⁺.
