Question

0.5 grams of iron wire was dissolved in 75 mL of h2so4 solution. And volume was increased to 250 ml with water 25 mL of this solution reducer 285 mL of n by tell kmno4 solution. The amount of pure iron present was​

Answer 1

Answer:

The iron is 100% pure.

Explanation:

22.90 ml 0.09672 N KMnO4 = 22.90 ml 0.09672 N FeSO4

Amount of FeSO4 in the solution = 0.3366g

Amount of iron in 0.3366g of FESO4 = 0.124g

Thus, percentage = 0.124 x 100 ÷ 0.124 = 100
