Question

today sunita and anita are perfoming an experiment to understand the double displacement reaction between aqueous potassium iodide and aqeous nitrate but they didn't find lead nitrate in the labortary .which of the folowing can be used as an alternative to lead nitrate .1rusting 2oxidation 3double displacement​

Answer 1

Answer:

aaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 2

Lead acetate can be used instead of lead nitrate.

Explanation:

• When aqueous lead nitrate is added to potassium iodide, Iodide ion displaces nitrate from lead nitrate and Nitrate displaces iodine from potassium iodide.
• The color of Potassium nitrate formed is white and that of lead nitrate is Yellow. The compound lead iodide is the precipitate formed.
• Now, if we do not get the lead nitrate we can use the Lead acetate.
• Lead acetate dissolves in water to give lead ion and acetate ion and on reacting with potassium iodide.
• The lead ion joins with the iodine ion to form lead iodide and potassium ion joins with acetate ion to form potassium acetate.
