.The addition of chemicals such as nitric acid (hno3) or sulfuric acid (h2so4) concentration is maintained by controlling the water ph (ph <2) purpose. Prevent adsorption of ions on the surface of the container.
More chemicals, such as naitrik acid (HNO3), sulphuric acid, (H2SO4) concentration is treated water samples by controlling the pH (pH < 2) objective is the prevention of adsorption surface area io container.
Fill the chemicals such as hydrochloric acid, photoelectric smoke detectors (HNO 3) or sulfuric acid (H SO 2 4 ) concentration to maintain the condition of control water samples by pH (pH< 2) for any purpose was to prevent absorption of AEON skin vessels.
