Thiocyanate and Mercury Chemistry

The video tutorial explains how to write the chemical formula for mercury(II) thiocyanate. It begins by identifying mercury as a transition metal and thiocyanate as a polyatomic ion. The tutorial then guides viewers through the process of balancing ionic charges to form the compound Hg(SCN)2. Additionally, it introduces the Pharaoh's Serpent reaction, a fascinating chemical demonstration involving mercury(II) thiocyanate.
