When potassium iodide solution is added to a solution of lead (II) nitrate in a test tube, a precipitate is formed.
(a) What is the colour of this precipitate? Name the compound precipitated.
(b) Write the balanced chemical equation for this rection.
(c) List two types of reactions in which this reaction can be placed.

Explanation

(a) The precipitate is yellow in colur. It is lead iodide `(PbI_(2))`.
(b) `Pb(NO_(3))_(2)(aq)+2Kl(aq)rarrPbI_(2)darr+2KNO_(3) (aq)`
(c ) (i) Double Displacement Reaction, (ii) Precipitation Reaction.
