D. `MO_(2)+H_(2)OtoM^(+)+OH^(-)`

Answer

To solve the question regarding the products obtained on hydrolysis of superoxide, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Superoxide Ion**:
Superoxides are compounds that contain the superoxide ion (O2^-). This ion is characterized by having one extra electron compared to the normal diatomic oxygen molecule (O2).

2. **Write the General Formula for Superoxide**:
The general formula for a superoxide can be represented as MO2, where M is a metal cation. For example, potassium superoxide can be represented as KO2.

3. **Understand Hydrolysis**:
Hydrolysis refers to the reaction of a substance with water. In this case, we are looking at the reaction of superoxide with water.

4. **Write the Hydrolysis Reaction**:
When superoxide (MO2) reacts with water (H2O), the products formed are:
- A hydroxide (M+OH^-)
- Hydrogen peroxide (H2O2)
- Oxygen gas (O2)

The balanced reaction can be represented as:
\[ 2MO2 + 2H2O \rightarrow 2M^+ + 2OH^- + H2O2 + O2 \]

5. **Example with Potassium Superoxide**:
For potassium superoxide (KO2), the hydrolysis reaction can be written as:
\[ 2KO2 + 2H2O \rightarrow 2KOH + H2O2 + O2 \]

6. **Conclusion**:
The products of the hydrolysis of superoxide are hydroxide ions (M+OH^-), hydrogen peroxide (H2O2), and oxygen gas (O2).

### Final Answer:
The products obtained on hydrolysis of superoxide are:
- Hydroxide ions (M+OH^-)
- Hydrogen peroxide (H2O2)
- Oxygen gas (O2)
