Question
In the double displacement reaction between aqueous potassium iodide and aqueous lead nitrate, a yellow precipitate of lead iodide is formed. While performing the activity if lead nitrate is not available, which of the following can be used in place of lead nitrate?(a) Lead sulphate (insoluble)(&) Lead acetate(c) Ammonium nitrate(d) Potassium sulphateAnswer
Solution
The correct answer is (b) Lead acetate.
In a double displacement reaction, the cations and anions of two different molecules switch places, forming two entirely different compounds. In this case, the reaction between potassium iodide and lead nitrate results in the formation of lead iodide and potassium nitrate.
If lead nitrate is not available, we need to replace it with a compound that contains lead (
