Boiling the water promotes the reaction 2 HCO 3 – → CO 3 2– + CO 2 + H 2 O by driving off the carbon dioxide gas. The CO 3 2– reacts with Ca 2+ or Mg 2+ ions, to form insoluble calcium and magnesium carbonates which precipitate out. By tying up the metal

calcium phosphate – Water Technology Report

Calcium phosphate forms as the result of a chemical reaction between calcium hardness (Ca) and orthophosphate (PO4). Chemically, the deposit is characterized as tricalcium phosphate (Ca3(PO4)2). The phosphate component is often contributed by a phosphate-based chemical additive, since polyphosphate is commonly used as a corrosion inhibitor.
