How can we make lead iodide dissolve in water?

• Lead iodide (PbI2) is sparingly soluble in water, meaning it only dissolves to a limited extent. However, there are a few ways to increase the solubility of lead iodide in water. PbI2-insoluble in cold water. Heat the solution until all of the lead iodide dissolves, above 80 degrees Celsius. Heating the solution causes the solubility to increase just enough to dissolve all of the lead iodide.
• 

• 1. Increase the temperature: The solubility of most solids in water increases with temperature. If you heat the water, more lead iodide will dissolve.

  
  

  2. Add a complexing agent: Adding a complexing agent, such as potassium iodide (KI), can increase the solubility of lead iodide in water. This is because the complexing agent forms a soluble complex with lead ions, which increases their solubility.

  
  

  3. Use a solvent mixture: Lead iodide is more soluble in a mixture of solvents than in water alone. Adding a small amount of a co-solvent, such as ethanol or acetone, to the water can increase the solubility of lead iodide.

  
  

  4. Increase the surface area: Breaking up the solid lead iodide into smaller pieces or grinding it into a fine powder can increase its surface area, which can increase the rate at which it dissolves in water.

  
  

  5. It is important to note that lead iodide is toxic and should be handled with care. If you are not experienced in working with hazardous chemicals, it is best to seek the assistance of a qualified chemist or laboratory technician.
