When you mix solutions of lead (II) nitrate and potassium iodide.
(i) What is the colour of the precipitate formed ? Name the compound involved.
(ii) Write a balanced chemical equation for the reaction
(iii) Is this a double displacement reaction ?

A

`Pb(NO_(3))_(2),KI`

B

`AgNO_(3),NaCl`

C

`Na_(2)SO_(4),BaCl_(2)`

D

`FeCl_(3),NH_(4)OH`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset((X))underset("Lead nitrate")(Pb(NO_(3))_(2))+underset("iodide (Y)")underset("Potassium")(2KI)tounderset(("yellow ppt."))underset("Lead iodide")(PbI_(2)darr)+underset("nitrate")underset("Potassium")(2KNO_(3))`
This is a double displacement reaction.
All others are also double displacement reactions but the precipitates formed are white in colour.
