Product Description:
Used in analytical chemistry as a reagent for the detection of ammonia and ammonium ions. It forms a yellow to orange precipitate when reacting with ammonium ions in neutral or slightly acidic solutions, making it valuable in qualitative inorganic analysis. Also employed in the preparation of other mercury-containing compounds and in some historical medicinal formulations, though such uses are now limited due to toxicity concerns.
