- A sample of iron ore weighing 800 mg was treated with HNO3 , boiled to dryness and redissolved in dilute HCl. After filtration and removal of undissolved silica, the liquid was passed through a Walden reductor. The collected sample was titrated with 0.0210 M KMnO4 , requiring 12.0 mL to reach the end point. Calc %Fe (55.845) in the ore.A 350 mg sample containing KClO3 was carefully reduced and treated with excess AgNO3. The resulting AgCl (MW = 143 g/mole) weighed 185 mg. Calculate the percentage of KClO3 (MW = 122 g/mole) in the samplePlease provide Typed solution.. And proper explannation
