So seeing all this different reactions, how do you think iron contaminants will behave with them?
1. with the solution of MnO2 + H2SO4 and Toluene, will the iron sulphate precipitate upon toluene addition as well?
2. in the procedure given by gsd, adding H2O2 dropwise, will the iron contaminants stay precipitated and the MnSO4 will stay in solution?
3. and with the citric acid addition, will there be any precipitate, iron maybe? (will it stay in solution mixed with the manganese ions?)
