Zinc oxide ( ZnO ) will react differently depending on the pH of the solution : in the case of acids : ZnO + 4H+ → Zn2+ + H2O .
Zinc oxide ( ZnO ) reacts differently depending on the pH of the solution : In acids : ZnO + 4H+ → Zn2+ + H2OIn bases : ZnO + H2O + 3OH- → [ Zn ( OH ) 4 ] 2-This effect can be used to separate different cations , such as zinc from manganese .
