- From the given question the correct answer is lead acetate.
- As we know that lead acetate is soluble in water so it will react with potassium iodide.
- We can use lead acetate as an alternative to lead nitrate.
- When potassium iodide reacts with lead acetate, it will form potassium acetate and yellow precipitate of lead iodide.
- Potassium iodide + Lead acetate → Lead iodide + Potassium acetate.
