However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in the very alkaline cement system. Page xstm John S. Chemical Society, Washington, DC. Dilute to 1 L in a volumetric flask and mix thoroughly. This solution is the standard and requires no further standardization.
