The basic ferric nitrate is very fine and even [?] the filter unless [?] great care is exercised. It is very prone to run through and so the filter [?] cannot be safely used. If the evaporation was carried far enough in the first place the separation of the iron is very complete. The method has the advantage that it requires very little attention when once started and other work may be carried on. It is also quite accurate in ist results - often one has acquired [??] of separation. The [?] required is very long when [duplicates?] are made. Unless the basic nitrate is well washed the aluminium salt may adhere to the fibres of the filter paper and appear with the iron. The ferric hydrate should also be thoroughly washed, not only to get rid of the ammonium chloride but especially of the potassium salts as they would increase the weight of the ferric oxide. Their presence may be detected by an alkaline reaction of the oxide.
