A certain mass of anhydrous oxalic acid is converted into , and , on heating in the presence of . The formed reacts completely with iodine pentoxide to liberate iodine. The iodine thus liberated required 300 ml of 0.2 N thiosulphate. The approximate mass (in g) of formed was
Answer:
4.00
Solution:
5CO + + . Thiosulphate: 0.300 × 0.2 = 0.06 eq, so = 0.03 mol and = 5 × 0.03 = 0.15 mol. Mass of = 0.15 × 28 = 4.2 ≈ 4 g. Ans: 4.
