Name : a metallic hydroxide soluble in excess of NH_( 4)OH .

Which will not give precipitate with NH_(4)OH Solution ?

A nitrate when mixed with common salt gives a white precipitate which is soluble in dilute NH_(4)OH . It is the nitrate of

A colourless solid A dissolves in water. The aqueous solution gives a white precipitate B when NaOH or NH_4 OH is added. B dissolves in excess of NaOH but not in excess of NH_4OH . BaCl2 solution added to a solution of A gives a white precipitate C which is insoluble in dilute HCI. A may be
