Ammonium iron sulfate - Preparation Method
Open Data Verified Data
ferrous sulfate and ammonium sulfate were each dissolved in a small amount of water. Each was heated to 60-70 °c and then poured into a porcelain dish. Acidification with a small amount of sulfuric acid and cooling with constant stirring. The crystals were filtered off with suction and washed with 50% ethanol to obtain pure ammonium ferrous sulfate.
