Limestone dolostone and marble.
Why does marble react to hydrochloric acid.
Click each image to see positive and negative results of the acid test.
Marble is made from an ionic compound called calcium carbonate with the chemical formula caco3.
Dolostone is a rock composed of almost entirely of dolomite.
When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid.
The acid test on rocks.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
It will produce a very weak fizz when a drop of cold hydrochloric.
Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
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.
Some rocks contain carbonate minerals and the acid test can be used to help identify them.
A strong effervescence can be observed.
In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
Marble reaction with hydrochloric acid.
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.
Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.
This compound consists of the carbonate ion co3 which has a negative charge of 2 and the calcium ion which has a positive charge of 2.
Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail.
