Name each of the following ions:
b. ClO3-
d. SO42-
f. CO32-
h. CH3COO-
i. HCO3-
To name each of the given ions, we need to understand the nomenclature rules for naming ions.
b. ClO3- : This ion is called the chlorate ion. The name is derived from the root of the element chlorine (Cl) and the -ate suffix, which indicates the presence of three oxygen atoms (O3) bonded to the chlorine atom.
d. SO42- : This ion is called the sulfate ion. The name is derived from the root of the element sulfur (S) and the -ate suffix, which indicates the presence of four oxygen atoms (O4) bonded to the sulfur atom.
f. CO32- : This ion is called the carbonate ion. The name is derived from the root of the element carbon (C) and the -ate suffix, which indicates the presence of three oxygen atoms (O3) bonded to the carbon atom.
h. CH3COO- : This ion is called the acetate ion. The name is derived from the acetate group, which consists of the root of the element carbon (C) and three hydrogen atoms (H3) bonded to a central carbon atom (C), followed by the -ate suffix.
i. HCO3- : This ion is called the bicarbonate ion. The name is derived from the bicarbonate group, which consists of the root of the element carbon (C) and one hydrogen atom (H), followed by the -ate suffix.
In general, when naming ions, it is important to identify the elements and the number of atoms of each element present in the ion. The suffixes -ate and -ite are commonly used to indicate the presence of oxygen atoms bonded to the central element in polyatomic ions.
