Limestone dolostone and marble.

Why does the metamorphic rock marble react with hcl acid. Why does marble react to hydrochloric acid. Find out by watching this video. Another geoshort educational video from scott brande. Wipe all acid off the rock sample with a paper towel.

The right hand rock is made of dolomite ca mg co 3 2. The reaction to acid is common among carbonate minerals that is the ones with co 3 as the anion. Learn vocabulary terms and more with flashcards games and other study tools. What is the reaction if any of the metamorphic rock marble to cold dilute hydrochloric acid.

Both rocks are called marble sometimes with a color modifier such as pink marble. Marble metamorphic reacts to hydrochloric acid. It will produce a very weak fizz when a drop of cold hydrochloric. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.

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. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o. Stone surface material may be lost all over or only in spots that are more reactive. Some rocks contain carbonate minerals and the acid test can be used to help identify them.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.

If the acid fizzes on your sample your rock is probably marble.

The other common mineral that makes up non foliated metamorphic rocks is quartz. Start studying metamorphic rocks. Why does marble react to hydrochloric acid. Calcite is caco 3.

That s why acid rain over time tends to degrade the surfaces of marble and limestone buildings. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o. 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.
