As2S3 is diarsenic triphosphate. hope this helped
In order to coagulate, there must be more ions. ... But there will be three ions when MgCl₂ dissociates (Mg²⁺ and 2Cl⁻), also, there will be more charge on Mg (Mg²⁺) than when KCl dissociates.
The salt As2S3 is a negatively charged salt. According to Hardy and Schulz rule, the ions having higher positive charge value will attract more negative charged ions. Here, Mg2+ has 2 positive ions where K+ has 1 positive ion. As the charge of Mg2+ is more, it'll attract more negative charged ions; so gravitational force will work downward and will easily settle down than K+. That's why MgCl2 is a better coagulant than KCl.

It is As2S3
arsenic trisulfide
2As3+ + 3S2- ---------> As2S3
Robert J. Kobliska has written: 'Temperature dependence of the Raman spectrum and the depolarization spectrum of amorphous As2S3'
The prefix di means two, and tri means three, so you have 2 Arsenic and 3sulfur, which comes to Ar2S3.

Minerals are materials that after millions of years take their most stable form. Crystals are structures that are always preferred relatively to the amorphous state. That's why almost every mineral is crystalline. For example As2S3 melts always results in an amorphous-glassy solid (phase change material used in CDs) but in the nature it is a crystalline solid known as orpiment (a yellow dye).
