1) Sulphur dichloride oxide, S02Cl2 is hydrolysed (decomposed) by water to sulphuric acid and hydrochloric acid. A sample of S02Cl2 was dissolved in sufficient water to produce 150 cm3 , and of the 25cm3 of the resultant solution required 15cm3 of 0.2 mol/dm3 sodium hydroxide for neutralisation. Calculate the mass of S02Cl2 in the sample. 2) When iodic (V) acid, HIO3 reacts with an aq solution of SO2, H2SO4 and iodine are produced. in an experiment, 0.1g of iodic (v) acid was reacted with excess sulphur dioxide and iodine formed were removed by heating. The sulphuric acid produced requred 28.4cm3 of 0.1mol/dm3 NaOH solution. Determine the equation for the reaction between iodic(V) acid and sulphur dioxide.
