You're asking about the boiling point of lead(II) sulfate (PbSO₄). However, lead(II) sulfate does not have a boiling point.

Here's why:

* Decomposition: Lead(II) sulfate decomposes before it reaches a boiling point. This means it breaks down into other substances when heated to a high enough temperature. The exact temperature of decomposition depends on the conditions, but it happens well before any boiling would occur.

* High Melting Point: Lead(II) sulfate has a very high melting point (around 1,170 °C or 2,138 °F). Boiling points are always higher than melting points, and due to the decomposition, lead(II) sulfate never reaches a temperature high enough to boil.
