or wny not?(i) What is observed when a solution ofpotassium iodide is added to a solutionof lead nitrate taken in a test tube?i) What type of reaction is this?1) Write a balanced equation to representthe above reaction. |
Answer» Lead nitrate = Pb[NO]₂ Potassium Iodide = KI When Lead Nitrate and Potassium Iodide are mixed we get Potassium Nitrate and an insoluble solid [ precipitate ] lead iodide. Colour of the precipitate formed is Yellow [ Lead Iodide ] KI + Pb[NO₃]₂ -----> KNO₃ + PbI₂ -----> UNBALANCED EQUATION 2Kl+ Pb[NO₃]₂ -----> 2KNO₃ + PbI₂----> BALANCED EQUATION This is an example of double displacement reaction. Also , as yellow precipitate is formed , this is also an example of precipitation reaction |
