A mixture containg As_(2)O_(3) and As_(2)O_(5) and required 20.10mL of 0.05N iodine for titration. The resulting solution is then acidified and excess fo KI was added. The liberated iondine required 1.1113g hypo (Na_(2)S_(2)O_(3) 5H_(2)O) for complete reaction. Calculate mass of mixture. The reactions are: AsO_(3) + 3l_(2) + 2H_(2)O rarr As_(2)O_(5) + 4H^(+) + 4I^(-) As_(2) O_(5) + 4H^(+) + 4l^(-) rarr As_(2) O_(3) + 2l_(2) + 2H_(2)O
