**Description**

|
|
|
Mercury(I)chloride is a dense yellowish-white solid that was once used as a chlorine donor for enriching colour, but owing to it's high toxicity and relatively low chlorine content (15%) when compared to the likes of polyvinyl chloride and parlon, it hasn't been widely used in around 40 years.
