Those forming soft scale such as ntagnesiumand calcium bicarbonates. 2, Those forming hard scale, such ascalcium sulphate. 3. Those which cause corrosion, as free acidsor magnesium chloride, which in the boiler combines with carbon-ates present to form neutral salts leaving hydrochloric acid free toattack the metal of the boiler. The bicarbonates are easily dealt with, since on the applicationof heat half the carbonic acid is driven off from the calcium car-bonate leaving the monocarbonate which is insoluble, and themagnesium carbonate comes down either as a hydrated oxide ormonocarbonate also insoluble.
