Jun 15, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
May 13, 2018 · In this video we'll balance the equation Ca(OH)2 + H2SO4 = CaSO4 + H2O and provide the correct coefficients for each compound. To balance Ca(OH)2 + H2SO4 = CaSO4 + H2O you'll need to be sure to .
May 01, 2002 · Chemicals are used in water well rehabilitation to remove products that are either contaminating the well water or blocking or plugging the well environment. Contamination can be the result of chemical infiltration into the well, such as the leakage of turbine oil into the well environment or the appearance of coliform bacteria from some contaminating source.
industrial formation of gypsum from sulphuric acid. . sulfuric ac Sulfur trioxide reacts with water and the reaction can be expressed as: However, water itself cannot be used for absorption as there is a large temperature rise, and a sulfuric acid mist is formed, which is difficult to handle Instead, sulfuric acid of about 98% concentration .
In its elemental form, calcium has a dull gray-silver appearance. Calcium is a reactive, soft metal that is a member of the alkaline earth elements.
