A drop of hydrochloric acid will fizz when it is in contact with carbonate minerals such as calcite and dolomite or carbonate rocks such as limestone, dolostone and marble.

The acid test is a method used to identify the presence of carbonate minerals, particularly calcite and dolomite, by observing their reaction to dilute hydrochloric acid.

It’s important to test with acid of the right strength, meaning not very strong.1 The solution I use works well for differentiating calcite and limestone from dolomite and dolostone. Here is how to mix up …

The reaction of dolostone with a 10% hydrochloric acid (HCl) – water solution is very slow and does not produce the characteristic fizz, which is produced by the reaction between HCl 10% and limestone.

Carbonate minerals and rocks (i.e. those that have calcite and/or dolomite in them, such as limestones, dolostone, and marble) are very common, and the quickest way to identify them is …

Oct 25, 2000 · Carbonate minerals and rocks (i.e. those that have calcite and/or dolomite in them, such as limestones, dolostone, and marble) are very common, and the quickest way to identify them is …

What to Learn: Your goal is to identify samples according to their reactivity with acid. Minerals that react are called chemical rocks, and minerals that don’t are called clastic rocks. Some chemical …

Perhaps the most diagnostic method for identifying limestone is an acid test. I go into detail about how to safely perform this test with common white vinegar in my Practical Rock Identification System.

Discover how to identify limestone with confidence in this comprehensive guide. Learn effective methods including the classic acid test, key visual characteristics, and tips for close examination …

If you place one drop of chilly hydrochloric acid on an item of dolomite, the response is weak or otherwise observed. Rather than seeing an evident fizz, you'll see a drop of acid externally of...
