Current Question (ID: 8616)

Question:

$\text{In the conversion, } \text{H}_2\text{SO}_4 \rightarrow \text{H}_2\text{S}_2\text{O}_8 \text{ which process occurs?}$

Options:

1. $\text{Oxidation}$
2. $\text{Reduction}$
3. $\text{Oxidation as well as reduction}$
4. $\text{Neither oxidation nor reduction}$

Solution:

$\text{In the conversion, } \text{H}_2\text{SO}_4 \rightarrow \text{H}_2\text{S}_2\text{O}_8 \text{, the oxidation state of sulfur remains } +6 \text{ in both compounds.}$ $\text{However, in } \text{H}_2\text{SO}_4 \text{, the oxidation state of oxygen is } -2 \text{. In } \text{H}_2\text{S}_2\text{O}_8 \text{ (peroxodisulfuric acid), two oxygen atoms are linked by a peroxide linkage } \text{(-O-O-)} \text{, and their oxidation state is } -1 \text{. The remaining six oxygen atoms have an oxidation state of } -2 \text{.}$ $\text{Since the oxidation state of some oxygen atoms changes from } -2 \text{ to } -1 \text{, which is an increase in oxidation state, this indicates that oxygen is oxidized.}$
