  Microbiologically induced calcite precipitation

  Microbiologically induced calcium carbonate precipitation (MICP) is a biogeochemical process that induces calcium carbonate precipitation within the soil matrix. Biomineralization in the form of calcium carbonate precipitation can be traced back to the Precambrian period. Calcium carbonate can be precipitated in three polymorphic forms, which in the order of their usual stabilities are ...

  What is Calcium Carbonate?

  Calcium carbonate, or CaCO3, comprises more than 4% of the earth''s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.

  Does Calcium Carbonate (CaCO3) effect water pH level?

  Answer (1 of 2): CaCO3 has very low solubility in water. It is a salt of a fairly strong base (calcium hydroxide ) and a weak acid (carbonic acid). In aqueous solution such salts undergo hydrolysis to give free OH ions, and so the solution will be basic in character. CO3(2) + H2O = HCO3() + ...
