To the given white powder form of zinc iodide ZnI2 the following two tests
are positive they are
1)n Iodide ion (I- ) 2) Zinc (II) ion (Zn2+ )
The other three tests are not give positive .
We know that compound has analysed by chemical into ions only. Hence here for the
given compound only two ions possible to give test. Tri iodide (I3 - ) is not formed.
