Chemical property
Zinc oxide is a famous white pigment, commonly known as zinc white. Its advantage is that H2S gas does not change black when encountered, because ZnS is also white. When heating, ZnO gradually changes from white and light yellow to lemon yellow, and the yellow fades after cooling. Using this characteristic, it is mixed into paint or added into a thermometer to make color-changing paint or color-changing thermometer. Because ZnO has convergence and certain bactericidal ability, it is often used in medicine to make ointment, ZnO can also be used as a catalyst.
Chemical formula: Reaction with NaOH: ZnO+2NaOH+H2O=Na2[Zn(OH)4]
