Question

In a reaction, a colorless iodide X reacts with a
colorless nitrate Y to produce another
colorless nitrate Z and a yellow colored iodide
W. One of the metal cations of the above four
salts is Pb. Identify X, Y, Z and W.
A
X = Pbl2; Y = KNO3; Z = Pb(NO3)2;
W = K!
X = KI; Y = Pb(NO3)2; Z = KNO3;
W = Pbl2
B.
X = Pb(NO3)2; Y = KI; Z = KNO3;
W = Pbl2
С
X = KI; Y = Pb(NO3)2; Z = Pbl2; W
= KNO3
D​
