The photolysis of water gives the substance:

Options

A. `OH^(-) + H^(+)`
B. `H_2 + OH^(-)`
C. `H_2+ O_2`
D. `H_2O + H_2O_2`

Answer

To solve the question regarding the photolysis of water and the substances produced, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photolysis**: Photolysis refers to the process where light energy (photons) is used to break down a chemical compound. In this case, we are looking at the photolysis of water (H₂O).

2. **The Reaction**: When water undergoes photolysis, it is split into its constituent ions. The general reaction can be represented as:
\[ 2 H_2O \xrightarrow{light} 2 H^+ + O_2 + 2 e^- \]
However, in the context of the question, we focus on the ions produced.

3. **Products of Photolysis**: The primary products of the photolysis of water are:
- Hydrogen ions (H⁺)
- Hydroxide ions (OH⁻)

4. **Analyzing the Options**: Now, we need to evaluate the given options:
- **Option 1**: H⁺ and OH⁻ - This is correct as these are indeed the products formed during the photolysis of water.
- **Option 2**: H₂ and OH⁻ - This is incorrect; H₂ is not produced in this reaction.
- **Option 3**: H₂ and O₂ - This is also incorrect as H₂ is not a product of the photolysis of water.
- **Option 4**: H₂O and H₂O₂ - This is incorrect; water and hydrogen peroxide are not the products of photolysis.

5. **Conclusion**: The only correct answer is Option 1, which states that the photolysis of water gives H⁺ and OH⁻ ions.

### Final Answer:
The photolysis of water gives the substances: **H⁺ and OH⁻**.
