what happens when sodium fluoride is reacted with silver nitrate and lead nitrate?

Question

what happens when NaF reacts with AgNO3 and with Pb(NO3)2
What happens KCl reacts with AgNO3 and with Pb(NO3)2
What happens when KBr and KI also both react with those same two reagents
colors and names of precipatates would help
Thanks A Lot

Answer 1

Sorry for my English.
First question 2 NaF + Pb(NO3)2= PbF2
Second question KCl + AgNO3 =AgCl (white)
and 2 KCl + Pb(NO3)2=PbCl2
Third question KBr +AgNO3 =AgBr
2 KBr + Pb(NO3)2 = PbBr2
KI +AgNO3 = AgI
2 KI + Pb(NO3)2 = PbBr2
Those are the compounds that have a Ksp very low

Answer 2

PbF2, PbCl2, PbBr2 and PbI2 (lead fluoride, chloride, bromide and iodide) are all pretty insoluble. The first three are all white, so adding lead nitrate is not a good way of testing for the halide ion. Lead iodide, however, is a brilliant yellow colour.
Using silver nitrate we find that silver fluoride (AgF) is soluble, so there is no precipitate, and no reaction.
Silver chloride, AgCl, is brilliant white, silver bromide, AgBr is off-white and silver iodide, AgI, is pale yellow.
