What is the correct name for the compound Ag_2CO_3?
A
Disilver carbon trioxide
B
Silver carbonite
C
Silver(II) carbonate
D
Silver carbonate
Verified step by step guidance1
Identify the cation and anion in the compound Ag_2CO_3. Here, Ag is the cation (silver) and CO_3 is the polyatomic anion (carbonate).
Determine the charge on the carbonate ion, CO_3, which is -2.
Since there are two silver (Ag) atoms, the total positive charge must balance the -2 charge from carbonate. This means each silver ion has a +1 charge.
Name the compound by stating the cation first followed by the anion. Because silver has only one common oxidation state here (+1), no Roman numeral is needed.
Combine the names to get the correct name: 'Silver carbonate'.
