Question

when we mixed the solutions of lead(II)nitrate and potessium iodide...what was the colour of the precipitate formed?give the name also.
write the balanced chemical equation for this reaction?

Answer 1

Pb(NO3)2 + KI -----> KNO3 + PbI2
white precipitate of LEAD [II] IODIDE is formed

Answer 2

Lead (II)  so
Pb (NO3)2  (in aqua )  + 2  K I (in aqua) ---->  2  K NO3  +  Pb I2

$Pb (NO3)_{2} (aqua) + 2 K I (aqua) => 2 K NO3 + Pb I_{2} (Solute)$

The lead iodide thus formed is yellow. it is not soluble in cold water. But in hot water it is soluble.
