What is PbP? Important knowledge about PbP.

1. Definition of PbP:
   PbP is not a clearly defined chemical substance. This could be understood as students having questions about the substance PbP₂, commonly known as Lead(II) Phosphate or Lead Phosphate in English. It is a solid, colorless, odorless substance that is insoluble in water. It is formed from Pb₂+ ions and phosphate PO₄₃-.

2. Properties: PbP₂

2.1 Physical properties of PbP₂
State: Solid, colorless.
Color: Colorless.
Smell: Odorless.
pH: Not applicable because PbP₂ is insoluble in water.

2.2 Chemical properties of PbP₂
PbP₂ is very slightly soluble in water and dilute acids.

3. Common chemical equation for PbP₂
   PbP₂ is involved in the reaction to form salts:
   Pb(NO₃)₂ + 2K₃PO₄ -> Pb₃(PO₄)₂ + 6KNO₃

4. Preparation of PbP₂

4.1 Laboratory preparation of PbP₂
Pb(NO₃)₂ + 2K₃PO₄ -> Pb₃(PO₄)₂ + 6KNO₃
An example of preparing PbP₂ in the lab is the reaction between lead(II) nitrate and potassium phosphate.

Note: PbP₂ is a toxic substance, not to be used in food and drinking water. Exposure and inhalation of PbP₂ dust should be limited.
