Does limestone have calcium? - AskingLot

2020-1-8  Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, clay minerals, pyrite, siderite, and other minerals.

What happens when carbonic acid reacts with calcium

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). Or, if there is more acid, two hydrogen ions will react with a carbonate to form carbonic acid – H2CO3 – which will decompose to form carbon dioxide – CO2 – which eventually bubbles off into the atmosphere, and water H2O.

2021-3-31  Coral reefs would not exist if it were not for the ability of coral polyps to secrete limestone or calcium carbonate. Sea water surrounding a coral is very rich in dissolved calcium carbonate, but the fluid inside the polyp cannot retain a large quantity of calcium carbonate, so it is laid down as microscopic needle-shaped crystals beneath and around the polyp.
