The method of liquid preparation
Now there is a method of liquid preparation, which is to adjust ten millimeters of ammonium acetate (Ammonium Acetate) to a specific pH value. First take an appropriate amount of ammonium acetate, put it in a purifier, slowly add water, and use a fine measurement tool to set it to ten millimeters. Then, use the pH measuring device to carefully observe its pH, or add acid or alkali, and carefully adjust it so that the pH value reaches the required level. After adjusting, check it again, so that it is accurate. In this way, the liquid can be used for subsequent matters. The method should be observed carefully, and there should be no omissions, in order to achieve its effect.
