Reference no: EM13180183

In a quality control analysis for sulphur impurity 5.6 g metal sample was burnt in a stream of oxygen and sulphur was converted into SO2 gas The SO2 gas then oxidizes to sulphate by using H2O2 solution towhich had been added 30 mL of 0.04M NaOH. the equation for reaction is : SO2(g) +H2O2(aq)+2OH(aq)-----> SO4^(-2)(aq)+ 2H2O(l) 22.48 mL of 0.024 M hcl was required to neutralizethe base remainig after oxidation reaction. calculate % of sulphur in given example.
