Chemical formula of white lead is _____

Explanation

To find the chemical formula of white lead, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Substance**: We need to determine the chemical formula for white lead. White lead is a compound commonly used in paints and is known for its white color.

**Hint**: Think about the common uses of white lead and what it is made of.

2. **Understand the Composition**: White lead is known as basic lead carbonate. It contains both carbonate ions (CO3) and hydroxide ions (OH).

**Hint**: Recall the components of basic lead carbonate and how they contribute to the overall formula.

3. **Write the Chemical Formula**: The chemical formula for white lead can be expressed as:
\[ \text{2 PbCO}_3 \cdot \text{Pb(OH)}_2 \]
This indicates that there are two carbonate groups and one lead hydroxide group in the compound.

**Hint**: Remember that the dot in the formula indicates that the components are part of a complex salt.

4. **Simplify the Formula**: The complete formula can also be simplified to:
\[ \text{2 PbCO}_3 \cdot \text{Pb(OH)}_2 \]
This shows that the compound consists of lead (Pb), carbonate (CO3), and hydroxide (OH) ions.

**Hint**: Look for patterns in how similar compounds are structured to help you remember the formula.

### Final Answer:
The chemical formula of white lead is:
\[ \text{2 PbCO}_3 \cdot \text{Pb(OH)}_2 \]
