ZnO + 2 HCl → ZnCl 2 + H 2 O. Solid zinc oxide will also dissolve in alkalis to give soluble zincates: ZnO + 2 NaOH + H 2 O → Na 2 [Zn(OH) 4] ZnO reacts slowly with fatty acids in oils to produce the corresponding carboxylates, such as oleate or stearate. ZnO forms cementlike products when mixed with a strong aqueous solution of zinc ...
