Mercury(II) Chloride
The formula of mercury chloride is HgCl2.
The chemical formula for mercuric chloride is HgCl2.
There are two chlorides of Mercury Mercury I chloride: Hg2Cl2 Mercury II chloride: HgCl2
Mercury(II) chloride, also known as mercuric chloride or corrosive sublimate, is a highly toxic compound that has been historically used in various applications like disinfectants, fungicides, and pesticides. However, its use has been greatly restricted due to its high toxicity and environmental hazards.
Examples: HgO, HgCl2, Hg2Cl2, HgI2, etc.
2Hg atoms and 2Cl atoms for a total of 4 atoms.
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
Mercury and chlorine in a hot sealed tube may form Mercuric chloride HgCl2
To calculate the grams of mercuric chloride needed, we must first find the molar mass of HgCl2 (molar mass = 200.59 g/mol). Then, calculate the moles of mercury in 5.11g (moles = 5.11g / molar mass of Hg = 0.032 mol). Since the ratio of HgCl2:Hg is 3:1 in the balanced equation, you would need 0.032 mol of HgCl2 (0.032 mol Hg x 1 mol HgCl2 / 1 mol Hg = 0.032 mol HgCl2) which is equal to 6.42g of HgCl2 (0.032 mol HgCl2 x molar mass of HgCl2 = 6.42g).
To prepare HgNH2Cl, first dissolve mercury(II) chloride (HgCl2) in water. Then add aqueous ammonia (NH3) to the solution until a white precipitate of mercury(II) amine chloride (HgNH2Cl) forms. The precipitate can be filtered and washed to isolate the compound.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
