Question

Suresh added few drops of Potassium lodide solution in lead nitrate solution in a test tube.
o
Write your observation of the change? What is the name of new compound formed.
()
Write a balance chemical equation for this reaction.
(i)
Name the chemical reaction involved in this reaction.​

Answer 1

Observation

A precipitate of yellow colour forms and settle down at the bottom of the container.

The new compound formed is Lead Iodide

$\rule{200}2$

i) The skeletal chemical equation of this reaction is

$\sf Pb(NO_3)_2 + KI \rightarrow KNO_3 + PbI_2$

The balanced chemical equation for this reaction would be

$\sf Pb(NO_3)_2(aq) + 2KI (aq) \rightarrow 2KNO_3(aq) + PbI_2(s)$

ii) Since there is an exchange in cations, or the metals are displacing each other in their salt solution, the reaction is Double Displacement Reaction. Also, since there is precipitate formation, it is Precipitation Reaction also.
