Marble Reacting With Hydrochloric Acid

Wipe all acid off the rock sample with a paper towel.

Marble reacting with hydrochloric acid.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. If the acid fizzes on your sample your rock is probably marble. 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.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Geologists can use dilute hydrochloric acid to help identify the cementing agent of sandstones. Stone surface material may be lost all over or only in spots that are more reactive. The combined reactants have a higher chemical potential than the combined products i e.

The reaction takes place spontaneously. Conical flask to hold the hydrochloric acid and marble chips boiling tube to hold and indicate whether or not carbon dioxide has been formed delivery tube to allow the gases to be passed through bowl of water to contain the water hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring. The rate of this reaction can be changed by changing the size of the marble chips. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Marble is a limestone or a dolostone that has been metamorphosed. Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung to stop the gas from escaping weighing boat to hold the marble chips in when weighing variables. Pieces of marble are thrown into hydro chloric acid.

It will have an acid reaction that is similar to the limestone or dolostone from which it was formed.
