To test for lime (calcium carbonate) in soil, you can use hydrochloric acid (HCl), which reacts with the lime to produce carbon dioxide gas, indicated by fizzing or bubbling.
The chemical reaction between lime (calcium carbonate, CaCO\(_3\)) and hydrochloric acid (HCl) is:
CaCO\(_3\) + 2HCl → CaCl\(_2\) + CO\(_2\) + H\(_2\)O.
In this reaction, calcium chloride (CaCl\(_2\)), carbon dioxide (CO\(_2\)), and water (H\(_2\)O) are produced.
There is an explanation video available below.
