Sufficient strong acid is added to the slurry to bring the pH down to less than about 5.0. It is a basic salt alkali earth metal or alkali metal. however, since hydroxides contain close to half as many electrons (hydrogen atoms) per ionic charge as oxygens do, even weak bases can outnumber strong acids due to their ability to absorb additional protons/electrons from other sources at equivalently lower energy cost required to produce hydroxides. A base is a substance that is used to neutralize acid is called a base. Is the salt zinc acidic or basic in nature? [O-][N+]([O-])=O, PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL, CHEMICAL OR PHYSICAL PROCESSES, e.g. 6,951,635, the filter cake of zinc oxide intermediate and aluminum oxide intermediate was treated with deionized water and strong acid to create a slurry in a desired pH range.
