If NaOH is added to an aqueous solution of zinc ions, a white precipitate appears and on adding excess NaOH, the precipitate dissolves. In this solution zinc exists in the
Cationic part
Anionic part
Both in cationic and anionic parts
There is no zinc in the solution
ions form a white precipitate of
which on reaction with the excess of the reagent dissolves forming a complex
.
The reactions are given as
