Which of the following statements is incorrect ?

Options

A. `H_(2)O_(2)` can act as an oxidising agent
B. `H_(2)O_(2)` can act as a reducing agent
C. `H_(2)O_(2)` has acidic properties
D. `H_(2)O_(2)` has basic properties

Explanation

To determine which statement is incorrect regarding hydrogen peroxide (H2O2), we will analyze each statement one by one.

### Step 1: Analyze the First Statement
**Statement:** H2O2 can act as an oxidizing agent.

**Analysis:** This statement is correct. Hydrogen peroxide (H2O2) is known to act as an oxidizing agent. For example, when H2O2 decomposes, it releases oxygen gas, which can oxidize other substances. The reaction can be represented as:
\[ 2 H_2O_2 \rightarrow 2 H_2O + O_2 \]

### Step 2: Analyze the Second Statement
**Statement:** H2O2 can act as a reducing agent.

**Analysis:** This statement is also correct. Hydrogen peroxide can act as a reducing agent under certain conditions. It can reduce other substances by donating electrons. The oxidation state of oxygen in H2O2 can change, allowing it to act as a reducing agent.

### Step 3: Analyze the Third Statement
**Statement:** H2O2 has acidic properties.

**Analysis:** This statement is correct. Hydrogen peroxide can release protons (H+) in solution, which gives it acidic properties. The dissociation can be represented as:
\[ H_2O_2 \rightleftharpoons H^+ + HO_2^- \]

### Step 4: Analyze the Fourth Statement
**Statement:** Hydrogen peroxide has basic properties.

**Analysis:** This statement is incorrect. Since H2O2 releases protons (H+), it exhibits acidic properties rather than basic properties. A substance that has basic properties would accept protons, but H2O2 does not do this.

### Conclusion
After analyzing all four statements, we find that the incorrect statement is:
**Option D:** Hydrogen peroxide has basic properties.

### Final Answer
The incorrect statement is **Option D**.
