Marble Reacting With Hydrochloric Acid

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

Marble reacting with hydrochloric acid. Wipe all acid off the rock sample with a paper towel. The rate of this reaction can be changed by changing the size of the marble chips. Marble is a limestone or a dolostone that has been metamorphosed. 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. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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.

Geologists can use dilute hydrochloric acid to help identify the cementing agent of sandstones. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. 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.

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. The combined reactants have a higher chemical potential than the combined products i e. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Marble chips made of calcium carbonate react with hydrochloric acid to make calcium chloride water and carbon dioxide calcium carbonate hydrochloric acid calcium chloride water.

If the acid fizzes on your sample your rock is probably marble.
