Sodium tungstate has formula Na,wow lead phosphate has formula `Pb_3(PO_4)_2`, formula for lead tungstate should be:

Options

A. `PbWO_4`
B. `Pb_2(WO_4)_3`
C. `Pb\\(WO_4)_2`
D. `Pb_3(WO_4)_4`

Explanation

To determine the formula for lead tungstate, we need to understand the components involved in the compound.

### Step-by-Step Solution:

1. **Identify the Components**:
- Sodium tungstate has the formula \( \text{Na}_2\text{WO}_4 \).
- Lead phosphate has the formula \( \text{Pb}_3(\text{PO}_4)_2 \).

2. **Identify the Ions**:
- From sodium tungstate, we have the tungstate ion \( \text{WO}_4^{2-} \).
- From lead phosphate, we have the lead ion \( \text{Pb}^{2+} \).

3. **Determine the Ratio of Ions**:
- The tungstate ion has a charge of \( -2 \), while the lead ion has a charge of \( +2 \).
- To balance the charges, we need one lead ion for every tungstate ion.

4. **Write the Formula**:
- Since we need one lead ion and one tungstate ion, the formula for lead tungstate will be \( \text{Pb}(\text{WO}_4) \).

5. **Final Formula**:
- Thus, the formula for lead tungstate is \( \text{PbWO}_4 \).
