(a)
Interpretation:
The chemical formula of chromate ion is to be stated.
Concept introduction:
A polyatomic ion refers to a charged chemical species that possess one or more elements attached with an oxygen atom. This type of anion is also called oxyanion. They are named by adding the suffix -ate. Some other oxyanions are named by adding the suffix -ite. Those oxyanions that are named by adding the suffix -ite have one oxygen atom less in their formula than the ions with the suffix -ate.
(b)
Interpretation:
The chemical formula of dichromate ion is to be stated.
Concept introduction:
A polyatomic ion refers to a charged chemical species that possess one or more elements attached with an oxygen atom. This type of anion is also called oxyanion. They are named by adding the suffix -ate. Some other oxyanions are named by adding the suffix -ite. Those oxyanions that are named by adding the suffix -ite have one oxygen atom less in their formula than the ions with the suffix-ate.
(c)
Interpretation:
The chemical formula of hydroxide ion is to be stated.
Concept introduction:
A polyatomic ion refers to a charged chemical species that possess one or more elements attached with an oxygen atom. This type of anion is also called oxyanion. They are named by adding the suffix -ate. Some other oxyanions are named by adding the suffix -ite.
