What happens when calcium carbonate reacts with

2020-5-15  Calcium carbonate reacts with sulfuric acid to form calcium sulphate and water, liberating carbon dioxide gas. Word: calcium carbonate + sulfuric acid = calcium sulfate + carbon dioxide + water. Similarly, what does calcium carbonate and Sulphuric acid make? Sulfuric acid react with calcium carbonate to produce calcium sulfate, carbon dioxide and water.

Biogenic Sulfuric Acid Attack and Case Studies

In describing BSA, De Belie8 and others1 state that sulfuric acid reacts first with calcium hydroxide in concrete to form gypsum. The gypsum then reacts with monosulfate to form ettringite, resulting in a large volume expansion that causes internal pressure and deterioration of the concrete matrix.1,8 Formation of ettringite through the reaction between gypsum and calcium aluminate hydrate (monosulfate) is also a major reaction of “conventional” or “classical” sulfate attack.3,9,10 However, ettringite or thaumasite, observed in other forms of sulfate

can be effective. Mineral lime (calcium carbonate) in these soils can be converted to gypsum by adding sulfur, sulfuric acid, or other acidic or acid-forming materials (see Table 1 for equivalent quan-tities of various soil amendments).

Any acid can dissolve soil calcium carbonate and release the bound calcium. Sulfuric acid is most common because it is relatively inexpensive ­ and adds less salt to the soil than hydrochloric acid (HCl). Sulfurous acid (H 2 SO 3) can be produced by com­ bustion of elemental sulfur in a sulfur burner, and it is a popular alternative to ...

2021-9-6  Gypsum is the neutral salt of a strong acid and strong base and does not increase or decrease acidity. Dissolving gypsum in water or soil results in the following reaction: CaSO 4 2H 2 O = Ca 2 + + SO 4 2- + 2H 2 O. It adds calcium ions (Ca 2 +) and sulfate ions (SO 4 2-), but does not add or take away hydrogen ions (H+). Therefore, it does ...
