Countries like Bangladesh, India, Thailand, Taiwan, mainland China, USA and around 60 more are affected by the arsenic poisoning of drinking water which poses a serious life threat to the lives of around 140 million people. Arsenic (At. No. 33) is known to be a dangerous toxin that can take lives if the intake is in large amts. Also it is carcinogenic causing cancer of bladder, skin, lungs, kidney etc. Water contaminated by arsenic typically contains arsenous acid and arsenic acid and their derivatives like As (III) and As (V). Arsenic acid tends to exist as the ions [HAsO4]2 and [H2AsO4]- . Arsenic Pentoxide is the inorganic compound having formula As2O5, which is highly unstable and more commonly found as As (III). Mainly these
