However sheltered areas on limestone and marble buildings and monuments show blackened crusts that have spalled peeled off in some places revealing crumbling stone beneath.
Secondly weight out 3 grams of marble chips for each concentration 3.
First you measure out 25cm3 of hydrochloric acid 2.
Marble reaction with hydrochloric acid.
However sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places revealing crumbling stone beneath.
You then fill a bowl with water along with a boiling tube and straight after attach the delivery tube at the end of the boiling tube 4.
Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
Pour the acid into the conical flask and add the marble chips 5.
Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail.
