Zinc oxide in a mixture with a about 0.5% iron(III) oxide (Fe2O3) is called calamine and is used in calamine lotion. There are also two minerals‚ smithsonite and hemimorphite‚ which have been called calamine historically (see: calamine (mineral). Zinc peroxide‚ ZnO2 .½ H2O‚ is a white to yellow powder that is used in antiseptic ointments. Zinc white is used as a pigment in paints and is more opaque than lithopone‚ but less opaque than titanium dioxide. It is also used in coatings for paper

The Effect of the Number of Drops of HCl and NaOH on the Net Change in the pH of Plant‚ Animal‚ and Nonbiological Solutions Research Question: How do plants and animals respond to changes in pH? Analysis Questions: Summarize the effects of HCl and NaOH on the tap water. HCl is an acid and when in tap water‚ dissociates into H+ and Cl-. Since it releases the H+ ion in the tap water‚ it raises the concentration of H+‚ which lowers the pH of the tap water. Unlike HCl‚ NaOH is a base. NaOH is a base because
