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 three different location viz. Lanka (Banaras Hindu University, campus), Mirzamurad and Babatpur which are relatively free from industrial pollution were examined during south-west monsoon period (July to September) in Varanasi using standaralize 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+.
