How to get the chemical formula for mecury (ii) chloride
The chemical formula for mercury (II) chloride is HgCl2.
To derive this formula, you need to determine the charges on the respective elements and balance them to achieve a neutral compound.
Mercury typically has a charge of +2 (II), while chloride has a charge of -1.
Since the charges must balance out, you need two chloride ions to balance the +2 charge of mercury. Therefore, the formula becomes HgCl2.
