Nov 06, 2008· Best Answer: This is the reaction between acid and calcium carbonate liberating carbon dioxide. In the surface layers of concrete, calcium carbonate forms slowly from the reaction of atmospheric carbon dioxide with calcium hydroxide. To prove this, when the surface layer has dissolved, the fizzing generally stops.
Sep 20, 2019· When calcium carbonate and hydrochloric acid meet in the stomach, a chemical reaction occurs. The combination of the acid naturally produced by the stomach and the base ingested in the form of calcium carbonate, either through a food source or a mineral supplement, will cause the neutralization of both compounds and the creation of byproducts that are neither acidic nor basic.
Mar 14, 2013· Efflorescence can form a thick layer on the surface, which can completely hide the concrete''s color or, as in your case, create unsightly white patches. Causes. Usually, efflorescence is primarily composed of calcium carbonate formed when leached calcium hydroxide (CH) from within the concrete reacts with carbon dioxide in the atmosphere.
Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.
Asked in Acids and Bases, Concrete and Cement. ... What is the reaction of calcium carbonate hydrochloric acid? ... When hydrochloric acid reacts with iron, you .
Both minerals are sulfides, and the acid reacts to release sulfur dioxide gas.The acid and the mineral together react with oxygen in the air, releasing CO2 gas.The acid reacts with the mineral to release CO2 gas that is bound into the crystal as carbonate ion.
Phosphate ions can combine with calcium ions to form calcium phosphate, a highly insoluble compound. Because it can increase phosphate concentration and is a weaker acid, phosphoric acid is a less effective scaleremoving agent than hydrochloric acid. Hydrochloric acid or sulfuric acid are more commonly used for industrial scale removal.
Chemically speaking this should work, but from a safety standpoint there are many issues, see below: Hydrochloric acid should work quite well for dissolving calcium/magnesium deposits (probably mostly carbonates and hydroxides). The protons of the acid will react with carbonate to make CO 2 and water, and with the hydroxide to make water. Both calcium chloride and magnesium chloride are very ...
effect of adding nanoparticles to the concrete mix on the flexure behavior of RC slabs. This study adopts the Calcium Carbonate (CaCa3) as a nanoparticles material. The second objective is to study the flexural behavior of RC slabs subjected to Hydrochloric Acid (HCl) solution either in mixing water or curing water. The third
Calcium hypochlorite is stored dry and cold, away from any acid, organic materials, and metals. The hydrated form is safer to handle. If accidentally mixed with a strong acid as, hydrochloric acid, a sudden outgassing of toxic and corrosive elemental chlorine can occur. Chlorine emanations are harmful and can create severe pulmonary problems.
Calcium carbonate reacts with an acid to produce bubbles on the surface of the crystal. To test your sample, drop dilute hydrochloric acid, lemon juice or vinegar onto the sample and watch for bubbles. Quartz does not react to a dilute acid.
Calcium carbonate, hydrochloric acid, and their interaction Calcium carbonate, hydrochloric acid, and their interaction How CaCO₃ reacts with HCl. Share Tweet Send [Deposit Photos] Let''s talk a little about the interaction between hy ...
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
Hydrochloric acid can be used to dissolve calcium carbonate and iron sulfide scales. However, iron sulfide chemically reacts with hydrochloric acid and produces hydrogen sulfide, a highly toxic gas having the odor of rotten eggs. Due to the high toxicity of hydrogen sulfide, safety provisions need to .

Jun 24, 2017· Calcium chloride and sulphuric acid react to form hydrochloric acid and calcium sulphate CaCl2 + H2SO4 = HCl + CaSO4 ( White ppt ) ammonium chloride + calcium hydroxide, calcium chloride ...
A more aggressive and destructive case of acid attack occurs when concrete is exposed to sulfuric acid. The calcium salt produced by the reaction of the sulfuric acid and calcium hydroxide is calcium sulfate which in turn causes an increased degradation due to sulfate attack. This process is illustrated below. H 2 SO 4 + Ca(OH) 2 Ca(SO) 4 + 2H 2 O

Phosphoric acid and trisodium phosphate are the main compounds used to dissolve concrete leftover from masonry work. Sometimes, that doesn''t do the trick. If that''s the case, use muriatic acid, an industrial grade of hydrochloric acid but only after washing away the other types of acids and donning all the right safety equipment.
Apr 22, 2013· HYDROCHLORIC ACID ATTACKThe chemicals formed as the products of reactionbetween hydrochloric acid and hydrated cement phasesare some soluble salts and some insoluble saltsSoluble salts, mostly with calcium, are subsequentlyleached out, whereas insoluble salts along withamorphous hydrogels, remain in the corroded dissolution, the ...
When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride, water and carbon HCl decomposes salts of weaker acids. So the equation of the reaction between calcium carbonate and HCl i...
Sep 23, 2007· Hydrochloric Acid on Concrete. ... But I guess that half the H2 it generates would react with the second reaction''s O2 to create H2O, so more CO2 is realeased to air than H2 ... Which leaves the H to bind with any free CO3 carbonate in the concrete, which''d produce water and CO2.
Calcium Carbonate. Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which contains both of those minerals).
