Answered: A solution of iron(II) sulfate was |

A solution of iron (II) sulfate was prepared by dissolving 10.00 g of FeSO4•7H2O (FW = 277.9) in water and diluting up to a total volume of 250 mL. The solution was left to stand, exposed to air, and some of the iron (II) ions became oxidized to ron (III) ions.

Preparation of standard Fe from FeSO4 • 7H2O

We were assigned to prepare a standard Fe for spectrophotometry determination of Fe. What we did is basically obtain a mass of FeSO4•7H2O, add a small a mount of distilled water before adding 18M of H2SO4 then dilute. My question is what exactly is the purpose of H2SO4? I asked my prof about it and she said it was to prevent Fe2+ from oxidizing. I'm not really satisfied with that answer
