I am looking for Ammonium Sulfate that has a yellowish color and has a rotten egg smell. I have perched some from another company but what I received was colorless and had no odor to it. Do you have the one I am looking for?
Ammonium Sulfate is colorless at room temperature. Ammonium Sulfide has yellowish color and rotten egg smell.
In Ammonium sulfate the yellowish color is due to reaction of S2O32− with concentrated sulfuric acid to form sulfur impurity.
Colorless ammonium sulfate is more pure.
