Marble is mostly made up of calcium carbonate which is caco3.

Marble reacting with hydrochloric acid equation.

Caco3 2hcl cacl2 h2co3. The combined reactants have a higher chemical potential than the combined products i e. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. H2co3 decomposes easily into h2o and co2 so the equation is.

Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2. Caco3 2hcl cacl2 h2o co2. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. The chemical equation that is going to be followed throughout the experiment will be. Stone surface material may be lost all over or only in spots that are more reactive. Pieces of marble are thrown into hydro chloric acid.

This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. Click each image to see positive and negative results of the acid test. Marble is especially sensitive to the degrading by acidic chemicals also to weathering. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

Acid rain is one of the top degradation agents for marble artefacts around the world. In words calcium carbonate reacts with hydrochloric acid to form calcium chloride water and carbon dioxide. Hydrochloric acid is hcl. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.

Acids carbonates salts carbon dioxide water marble is caco3 2hcl caco3 cacl2 co2 h2o. Marble reaction with hydrochloric acid. The reaction takes place spontaneously. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
