Answer #1

I think Answer should be KNo3 because

Due to common ion effect solubility is always decreased. Here pb(Cro4)2 and pbcl2 contain Common ion pb2+ , pb(Cro4)2 and Na2Cro4 contain Common ion Cro42- so solubility of Pb(Cro4)2 will be decreased after adding pbcl2 and Na2Cro4.

Now after adding Nh4Cl , Pbcl2 is formed that is a precipitate , insoluble in water whereas after adding KNO3 , Pb(No3)2 is formed which has high Ksp value so it is highly soluble in water. So KNo3
