KBr is an ionic compound so we use in the formation of pellet
on the other other hand it should be dried before using because it is hygroscopic nature at room temparature
KBr had Zero Dipole moment beacuse of it's iomiic nature

Answer / s.ramakrishna
kbr is ir inactive,it does not shows any peaks in ir region and no response gives in 4000 to 400cm- and also kbr shows better resolution than kcl
