Interpretation:
The oxyanions sulfate and sulfite needs to be compared.
Concept introduction:
In an oxyanion, the non metal is bonded with one or more oxygen atoms. This is also known as polyatomic ion. Depending on the number of oxygen atom, the oxidation state of the central non-metal is determined. The suffix used in the name of the polyatomic ion depends on the oxidation state.
Answer to Problem 107A
When sulfur covalently bonds with three oxygen atoms then it called sulfite. The formula is
And when sulfur covalently bonds with four oxygen atoms then it called sulfate. Its formula is
Explanation of Solution
Electron configuration of sulfur is as follows:
Sulfur can exists in the +4 by losing its four
Thus, when sulfur covalently bonds with three oxygen atoms then it called sulfite. The formula is
And when sulfur covalently bonds with four oxygen atoms then it called sulfate. Its formula is
