I am no chemist, nor did I pick up much understanding of chemical reactions in school. But I would like a basic understanding of how "reactive" and "potent" sulfuric acid is on rock; i.e., whether or not, and if so, how fast it would dissolve or otherwise affect the rock. Now, I know there are various types of rocks, and I'm sure this question could be too broad if not narrowed to some extent. So let me give some specifics.
Assuming a highly concentrated sulfuric acid (98%; but weaker, if perchance that would be more potent against the particular rock):
- Will the sulfuric acid affect (dissolve or otherwise) it at all (and the ideal concentration to do so)?
- If it affects it, then:
- how fast would it dissolve/otherwise a solid piece of rock (not powder), say 1 cubic inch (though I'm looking for rate answers, so whatever the evidence gives as a rate works)?
- Is rate affected by pressure (i.e., the rock "sitting" in the acid versus a pressurized spray of the acid on it)?
- How much faster(?) would it dissolve it if the rock was powdered?
- What are the general products/results left after the effect?
(Perhaps the chemically diverse make-up of these rocks makes answering not feasible.)
- Marble (perhaps reacts similar to limestone, "Geologists use the term 'marble' to refer to metamorphosed limestone"?)
While I have no problems with you giving in your answer the chemical reactions involved, I desire at least a "laymen's" summary of what occurs to each.
(Also, feel free to re-tag if there are some viable tags I was not aware of.)
