When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Why does the metamorphic rock marble react with hcl acid.
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.
Some rocks contain carbonate minerals and the acid test can be used to help identify them.
Limestone dolostone and marble.
Dolostone is a rock composed of almost entirely of dolomite.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
Wipe all acid off the rock sample with a paper towel.
Stone surface material may be lost all over or only in spots that are more reactive.
Marble metamorphic reacts to hydrochloric acid.
Learn vocabulary terms and more with flashcards games and other study tools.
The reaction to acid is common among carbonate minerals that is the ones with co 3 as the anion.
Why does marble react to hydrochloric acid.
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.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
Start studying sedimentary rocks and metamorphic rocks.
Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o.
Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o.
That s why acid rain over time tends to degrade the surfaces of marble and limestone buildings.
Calcite is caco 3.
Start studying metamorphic rocks.
Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid.
The acid test on rocks.
The right hand rock is made of dolomite ca mg co 3 2.
Both rocks are called marble sometimes with a color modifier such as pink marble.
What is the reaction if any of the metamorphic rock marble to cold dilute hydrochloric acid.
