Name each of the following ionic compounds containing a polyatomic ion. (Type your answer using the format copper(II) chloride for CuCl2.)
1.Sn(SO4)2
thanks
In the old days I would have called this stannic sulfate.
Today I would name it as tin(IV) sulfate.
Frankly, I liked stannic sulfate better, the new format sounds like I'm saying "ten four" and that sounds like I'm playing detective.
10, 4 and out.
can u explain?
To name an ionic compound containing a polyatomic ion, follow these steps:
Step 1: Identify the cation and the anion in the compound.
In this case, the cation is Sn (tin) and the anion is (SO4)2- (sulfate).
Step 2: Determine the charge of the cation and the anion.
The charge of the cation is determined by the Roman numeral in parentheses, if applicable. In this case, Sn is a transition metal, so we need to specify its charge. The (SO4)2- ion has a charge of -2.
Step 3: Use the crisscross method to determine the subscripts.
The charge of the cation determines the subscript of the anion, and vice versa. To balance the charges, the subscript of the cation becomes the subscript of the anion, and the subscript of the anion becomes the subscript of the cation. In this case, since the cation Sn has a charge of +2, and the anion (SO4)2- has a charge of -2, we have Sn2(SO4)2.
Step 4: Write the name of the cation first, followed by the name of the polyatomic ion.
The name of the cation is "tin", and the name of the (SO4)2- polyatomic ion is "sulfate". Hence, the name of the compound is tin(II) sulfate.
Therefore, the name of the compound Sn(SO4)2 is tin(II) sulfate.
