Why does the metamorphic rock marble react with hcl acid.

Marble metamorphic reacts to hydrochloric acid. The acid test on rocks. Stone surface material may be lost all over or only in spots that are more reactive. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o.

Start studying sedimentary rocks and metamorphic rocks. Both rocks are called marble sometimes with a color modifier such as pink marble. Some rocks contain carbonate minerals and the acid test can be used to help identify them. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Start studying metamorphic rocks. Dolostone is a rock composed of almost entirely of dolomite.

The calcium carbonate is more soluble in solutions with a higher h concentration and it can also react in the same way as calcium carbonate and hcl. The right hand rock is made of dolomite ca mg co 3 2. Marble fizzes with acid because it is composed of the mineral calcite calcium carbonate caco3 which reacts with acids to form the gas carbon dioxide and it is the release of the carbon dioxide. The other common mineral that makes up non foliated metamorphic rocks is quartz.

Find out by watching this video. Why does marble react to hydrochloric acid. Why does marble react to hydrochloric acid. Calcite is caco 3.

The reaction to acid is common among carbonate minerals that is the ones with co 3 as the anion. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Wipe all acid off the rock sample with a paper towel. That s why acid rain over time tends to degrade the surfaces of marble and limestone buildings.
