(2010) [5] prepared
zinc hydroxide nitrate (ZHN) and then performed the anionic exchange with a boron-containing compound.
According to the literature [8], during exposure in chloride environment, the layer of corrosion products may be formed by compounds such as ZnO, Zn[(OH).sub.2], ZnC[O.sub.3], and [Zn.sub.5][(OH).sub.8][Cl.sub.2] x [H.sub.2]O, wherein
zinc hydroxide predominates in the chloride-containing medium [9].

Zinc hydroxide nitrate (ZHN), [Zn.sub.5][(OH).sub.8][(N[O.sub.3]).sub.2]2[H.sub.2]O, was prepared by adding aqueous ammonium hydroxide to a solution of zinc nitrate.
Zinc oxide nanoparticles were synthesized by a modified wet chemical method involving the precipitation of
zinc hydroxide, Zn[(OH).sub.2], from the reaction of 0.1 mol zinc nitrate and 0.2 mol sodium hydroxide solutions followed by overnight drying of the precipitates at 80[degrees]C to form ZnO [19].
Corticotropin-zinc hydroxide (sterile corticotropin
zinc hydroxide suspension USP) is a sterile aqueous suspension of purified corticotropin with
zinc hydroxide for repository action.
ANI Pharmaceuticals (NASDAQ:ANIP), an emerging leader in the speciality pharmaceutical industry, has completed the acquisition of the NDAs for purified corticotropin gel and corticotropin
zinc hydroxide from Merck, an international developer, manufacturer and distributor of pharmaceuticals.
When concentration of Zn[Cl.sub.2] in the working solution was 0,05 M the formation of precipitate of
zinc hydroxide there were observed.
Unfortunately, when zinc(II)-ions react with hydroxide ions in an aqueous medium,
zinc hydroxide is precipitated (1).
