Why Does Marble React To Hydrochloric Acid

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.

Why does marble react to hydrochloric acid.

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. A strong effervescence can be observed.

The acid test on rocks. 1question marble chips calcium carbonate react with hydrochloric acid in an exothermicreaction calcium carbonate hydrochloric acid calcium chloride water carbon dioxidewhen excess marble chips are added to dilute hydrochloric acid the rate of the reaction startsoff fast then gets slower until the reaction stops why does the reaction rate get slower a. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

Pieces of marble are thrown into hydro chloric acid. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. 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. Caco3 2hcl h2o co2 this is the reaction we will be investigating.

Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. It will produce a very weak fizz when a drop of cold hydrochloric. Click each image to see positive and negative results of the acid test. Why would marble rock react with hydrochloric acid marble is made from calcium carbonate.

Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Marble is made from an ionic compound called calcium carbonate with the chemical formula caco3. Marble reaction with hydrochloric acid. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

Some rocks contain carbonate minerals and the acid test can be used to help identify them.
