Question

when you have mixed the solution of lead nitrate and postassium iodine .
1. what was the colour and name of precipitate.
2. write balanced equation .
3. is this also a double displacement reaction

Answer 1

Hi there !!

Lead nitrate = Pb[NO]₂
Potassium Iodide = KI



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

Answer 2

1.colour is yellow
Product is PbI2
3.It is a double displacement reaction
