Question

when you have mixed the solutions of lead nitrate and potassium iodide 1)what was the colour of precipitate formed and can you name the precipitate? 2)write the balanced chemical equation 3)Is this 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

Hey,

1. Yellow precipitate (Lead Iodide)

2. Pb(NO3)2+2KI → PbI2+2KNO3

3. YES

Hope it helps☺
