How is co2 released from limestone
Web15 jun. 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more … Web1 dag geleden · Instead, the reaction produced only heat, a damp sigh of water vapor — and a Roman-like cement mixture bearing small, white, calcium-rich rocks. Step two was to test this cement. The team created concrete with and without the hot-mixing process and tested the two side-by-side. Each block of concrete was broken in half.
