Which does not appear in the case of hydrochloric acid
Sandstone and marble contain calcium carbonate and other substances, encountered hydrochloric acid will bubble! Granite is a kind of silicate stone! Therefore, hydrochloric acid does not bubble!
Also known as sand rock is sandstone, due to crustal movement of the earth, sand and cement (siliceous material, calcium carbonate, clay, ferric oxide, calcium sulfate) a sedimentary rock formed by long-term pressure compression bonding.
Granite: mainly composed of quartz, feldspar, hornblende, pyroxene, olivine and biotite composition, is a kind of silicate stone, the composition of silica based, accounting for about 65% ~ 75%. (acid)
Marble: belong to carbonate stone, the main component of calcium carbonate, accounting for more than 50%, and other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide, etc.. There are usually a lot of mineral grains. (alkaline)
