Calcite is a mineral that makes up limestone and chalk. Limestone and chalk are sedimentary rocks found in many parts of the world. Chalk is a fine grained form of limestone.
Jun 15 2008 Limestone is mostly made up of the mineral calcium carbonate CaCO3. This is not very soluble so rocks dont 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 acid two hydrogen ions will
Jun 16 2021 1. Soak overnight in oxalic acid to remove iron deposits. If your quartz crystals have only a small outer layer of iron you should be able to thoroughly clean them by soaking them in a weak solution of oxalic acid overnight.
