Why does marble react to hydrochloric acid.

Pieces of marble are thrown into hydro chloric acid. The acid test on rocks. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. An investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Caco3 2hcl h2o co2 this is the reaction we will be investigating. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. A strong effervescence can be observed. Marble reaction with hydrochloric acid. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Why would marble rock react with hydrochloric acid marble is made from calcium carbonate. Some rocks contain carbonate minerals and the acid test can be used to help identify them. Dolostone is a rock composed of almost entirely of dolomite.

It will produce a very weak fizz when a drop of cold hydrochloric. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. Marble is made from an ionic compound called calcium carbonate with the chemical formula caco3. Limestone dolostone and marble.

Stone surface material may be lost all over or only in spots that are more reactive.
