Hello everybody! I have to make an interesting fertilizer for plants in Horticulture study. So I have to make citric iron (II) - C12H10Fe3O14 with iron (II) (22 %) and 3,5 pH (about 5 litre of it).
I can choose 3 components -
- FeSO 4 - ferrous sulphate
- C6H8O7 - citric acid -
- C6H6Na2O7 - disodium citrate
I have everything to do it - alcohol, acid, dishes, everything to make it in higher temperature.
If i would like make lower than 3,5 pH I have to add more citric acid or disodium citrate?
