These are hypochlorous acid (HOCl) and the less active hypochlorite ion (OCl). The pH of the water determines how much hypochlorous acid is formed. While sodium hypochlorite is used, hydrochloric acid (HCl) is used to lower the pH. Sulfuric acid (H 2 SO 4) can be used as an alternative for acetic acid.

· Exposing the deep earth to air and water also causes chemical reactions that produce sulfuric acid, which can leak into drainage systems. Air quality is also compromised by gold mining.
Mining. The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Openpit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
