1.	(i) What is observed when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube? (ii) What type of reaction is this? (iii) Write a balanced chemical equation to represent the above reaction.
Answer» SOLUTION :(i) A yellow precipitate of LEAD iodide `(PbI_(2))` is formed. (II) Precipitation reaction/Double displacement reaction. (III) `underset("Lead NITRATE")(Pb(NO_(3))_(2)(aq))+underset("iodide")underset("Potassium")(2KI(aq))rarrunderset(("Yellow ppt."))underset("Lead iodide")(PbI_(2)(s))+underset("nitrate")underset("Potassium")(2KNO_(3)(aq))`
