Identify the acid which matches the following description
The acid on mixing with lead nitrate solution produces a white precipitate which is insoluble even on heating

Explanation

To solve the problem, we need to identify the acid that, when mixed with lead nitrate solution, produces a white precipitate that is insoluble even on heating. Let's break down the solution step by step.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- We know that lead nitrate has the chemical formula Pb(NO3)2. When an acid is mixed with this solution, we are looking for a reaction that produces a white precipitate.

2. **Identifying the White Precipitate**:
