Question
A certain oxyacid is derived from the oxyanion SO32-. The formula for the oxyacid is:
- H2SO4
- HSO3
- H2SO3
- H3SO3
- none of the above.
Solution
The oxyacid derived from the oxyanion SO3^2- is H2SO3.
Here's the step-by-step explanation:
-
An oxyanion is a polyatomic ion that contains one or more oxygen atoms and one atom of another element. In this case, the other element is sulfur (S).
-
The charge of the oxyanion SO3^2- is -2.
-
An oxyacid is a compound that contains hydrogen, oxygen, and another element. The hydrogen atom(s) can be replaced by a metal to form a salt.
-
To form an oxyacid from an oxyanion, hydrogen ions (H+) are added to balance the charge of the oxyanion.
-
Since the charge of the oxyanion SO3^2- is -2, two hydrogen ions (each with a charge of +1) are needed to balance the charge.
-
Therefore, the formula for the oxyacid derived from the oxyanion SO3^2- is H2SO3.
