Water transpoted through Lead pipes becomes poisonous due to the formation of `:`

Options

A. `PbO`
B. `PbO_(2)`
C. `Pb(OH)_(2)`
D. `Pb_(3)O_(4)`

Answer

To answer the question about why water transported through lead pipes becomes poisonous, we can break down the solution step by step.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- When water comes into contact with lead pipes, a chemical reaction can occur between lead (Pb) and oxygen (O2) in the presence of water (H2O).

2. **Formation of Lead Compounds**:
- The reaction can lead to the formation of several lead compounds. The relevant compounds that can form include:
- Lead(II) oxide (PbO)
- Lead(IV) oxide (PbO2)
- Lead hydroxide (Pb(OH)2)
- Lead(II) oxide (Pb3O4)

3. **Identifying the Toxic Compound**:
- Among these compounds, lead hydroxide (Pb(OH)2) is particularly toxic. This is the primary concern when water is transported through lead pipes.

4. **Chemical Reaction**:
- The simplified reaction can be represented as:
\[ 2 \text{Pb} + \text{O}_2 + 2 \text{H}_2\text{O} \rightarrow 2 \text{Pb(OH)}_2 \]
- This shows that lead reacts with oxygen and water to form lead hydroxide.

5. **Conclusion**:
- Therefore, the water becomes poisonous due to the formation of lead hydroxide (Pb(OH)2) when it interacts with lead pipes.

### Final Answer:
Water transported through lead pipes becomes poisonous due to the formation of **lead hydroxide (Pb(OH)2)**.
