Which of the following statements is incorrect for hydrogen peroxide ?

Options

A. It is stored in plastic bottles in dark
B. It acts as an oxidizing as well as a reducing agent.
C. It is used as a bleaching agent.
D. It has acidic as well as basic properties.

Answer

To determine which statement about hydrogen peroxide (H2O2) is incorrect, let's analyze each statement one by one.

### Step 1: Analyze the first statement
**Statement:** Hydrogen peroxide is stored in plastic bottles in the dark.

**Analysis:** This statement is correct. Hydrogen peroxide decomposes when exposed to light, breaking down into water (H2O) and oxygen (O2). To prevent this decomposition, it is stored in opaque plastic bottles and kept away from light.

### Step 2: Analyze the second statement
**Statement:** Hydrogen peroxide acts as an oxidizing agent as well as a reducing agent.

**Analysis:** This statement is also correct. Hydrogen peroxide can act as an oxidizing agent by accepting electrons (or providing oxygen) and as a reducing agent by donating electrons (or removing oxygen). For example:
- As an oxidizing agent: H2O2 + 2H+ → 2H2O
- As a reducing agent: H2O2 → O2 + 2e- + 2H+

### Step 3: Analyze the third statement
**Statement:** Hydrogen peroxide is used as a bleaching agent.

**Analysis:** This statement is correct. Hydrogen peroxide is widely used as a bleaching agent in various applications, including hair bleaching and in laundry detergents.

### Step 4: Analyze the fourth statement
**Statement:** Hydrogen peroxide has acidic as well as basic properties.

**Analysis:** This statement is incorrect. Hydrogen peroxide does exhibit acidic properties (it can donate protons), but it does not have basic properties. It does not accept protons or react as a base. The reactions involving H2O2 show that it can produce H+ ions, confirming its acidic nature but not its basicity.

### Conclusion
The incorrect statement regarding hydrogen peroxide is: **"It has acidic as well as basic properties."**
