Why Does The Metamorphic Rock Marble React With Hcl Acid

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

Why does the metamorphic rock marble react with hcl acid.

Stone surface material may be lost all over or only in spots that are more reactive. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Find out by watching this video.

Marble metamorphic reacts 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. 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.

Both rocks are called marble sometimes with a color modifier such as pink marble. Start studying metamorphic rocks. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. The other common mineral that makes up non foliated metamorphic rocks is quartz.

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. Limestone dolostone and marble. Start studying sedimentary rocks and metamorphic rocks.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Wipe all acid off the rock sample with a paper towel. Why does marble react to hydrochloric acid. It will produce a very weak fizz when a drop of cold hydrochloric.

Dolostone is a rock composed of almost entirely of dolomite. That s why acid rain over time tends to degrade the surfaces of marble and limestone buildings. The right hand rock is made of dolomite ca mg co 3 2. Why does marble react to hydrochloric acid.

Some rocks contain carbonate minerals and the acid test can be used to help identify them. The acid test on rocks. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o. Calcite is caco 3.
