AgI(silver iodide)

Write the equation

#AgNO_3+ NO_3^-1 + Cl_2^-1 + I_2^-1#

Our question is little bit wrong AgNO3 will not react with NO3 ions
But still to practice take Bromine ions

#Ag^- + I^+ = AgI#

#Ag^+ + Cl_2^- = AgCI#

#Ag^+ + Br^- = AgBr#

Ksp of AgI = #8.3 xx 10^(–17)#
Ksp of AgCl = #1.77 xx 10^(¯10)#
Ksp of AgBr =#5.4 xx 10^ (−13#

As Ksp of AgI is the least so the AgI will precipitate first.
