Question

In the double displacement reaction between aqueous potassium iodide and aqueous lead nitrate solution, a yellow precipitate of lead iodide is obtained. While performing the activity if lead nitrate is not available, which of the following can be used in the place of lead nitrate?

• A. Lead sulphate
• B. Lead acetate
• C. Ammonium nitrate
• D. Potassium sulphate

Answer 1

The correct option is B Lead acetate

Lead sulphate is insoluble, therefore it will not form an aqueous solution.

Also, other salts, ammonium nitrate and potassium sulphate do not posses the lead ion, therefore lead iodide can not be formed using them.

Therefore, lead acetate can be used in place of lead nitrate.
