Question

when you mix solutions of lead (II) nitrate and potassium iodide
i) wht is the color of the precipitate formed. Name the compound formed.
ii) balanced chemical equation.
iii) is this double displacement reaction??
Urgent answer needed :-)

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

The colour of precipitate is yellow. Compound- lead iodine ( PbI2)

It is double displacement reaction

Pb(NO3)2 + 2KI = PbI2 + 2KNO3
