  • Acid sulfate soils NSW Environment Energy and Science

    Acid sulfate soils are found in every coastal estuary in NSW. Because of their estuarine origin they are usually found at elevations less than 1 metre above sea level. Acid sulfate soils are common in mangrove and saltmarsh areas. They underlie floodplains levees and backswamps. Acid sulfate soils may affect more than 260 000 hectares of land.

  • What Are the Effects of Sulfuric Acid (with pictures)

    A sulfuric acid burn should be irrigated profusely with water. The effects of sulfuric acid on metals are typical of a strong acid it will react with those metals that are more reactive than hydrogen to form a metal sulfate salt and release hydrogen gas. It will react in this way with many common metals including iron zinc and aluminum.
