Is a reaction of any acid and any metal carbonate going to be endothermic like ethanoic acid Q. Water is trying to pull the calcium carbonate apart but the attraction of calcium ion to the carbonate ion is too strong, so the shell stays intact. This reaction generates the very flammable element H2, or hydrogen gas. Similarly, when calcium carbonate reacts with hydrochloric acid, increasing the concentration of the acid speeds up the rate of reaction as long as enough calcium carbonate is present. contributor to alkalinity, through precipitation of calcium carbonate. This acid product in this reaction is unstable and breaks down to form carbon dioxide and water. included in the results section of your final lab report. Two of the polymorphs of CaCO 3, calcite and aragonite, can form under different local.
