Content determination
Take about 0.5g of this product, weigh accurately, add 10ml of chloroform, warm slightly to melt the vaseline, add 10ml of 0.5mol/L sulfuric acid solution, stir to dissolve the zinc oxide, and determine according to the method under zinc oxide, starting from "add 1 drop of 0.025% methyl red ethanol solution". Each 1ml of disodium ethylenediaminetetraacetic acid titration solution (0.05mol/L) is equivalent to 4.069mg of ZnO.
