Why Does The Metamorphic Rock Marble React With Hcl Acid

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.

Why does the metamorphic rock marble react with hcl acid.

Find out by watching this video. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Wipe all acid off the rock sample with a paper towel. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. The right hand rock is made of dolomite ca mg co 3 2. Calcite reacts with hcl to produce calcium chloride carbon dioxide and water caco3 2 hcl cacl2 co2 h2o. 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. Calcite is caco 3. Stone surface material may be lost all over or only in spots that are more reactive. That s why acid rain over time tends to degrade the surfaces of marble and limestone buildings.

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 reaction to acid is common among carbonate minerals that is the ones with co 3 as the anion. Start studying sedimentary rocks and metamorphic rocks.

If the acid fizzes on your sample your rock is probably marble. Dolostone is a rock composed of almost entirely of dolomite. It will produce a very weak fizz when a drop of cold hydrochloric. Limestone dolostone and marble.

Why does marble react to hydrochloric acid. Some rocks contain carbonate minerals and the acid test can be used to help identify them. Learn vocabulary terms and more with flashcards games and other study tools. Marble metamorphic reacts to hydrochloric acid.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Start studying metamorphic rocks. The other common mineral that makes up non foliated metamorphic rocks is quartz. Why does marble react to hydrochloric acid.
