(ii) What type of reaction is this?
(iii) Write a balanced chemical equation to represent the above reaction.

Answer 1

(i) A yellow precipitate of lead iodide will be formed.

(ii) This is a double displacement reaction.

(iii) $Pb{\left(N{O}_3\right)}_2\left(aq\right)+2KI\left(aq\right)$ $\to$ $Pb{I}_2\left(s\right)$ + $2KN{O}_3\left(aq\right)$
