Alkalinity And Hardness Relationship

Alkalinity is often related to hardness because the main source of alkalinity is usually from carbonate rocks (limestone) which are mostly CaCO3. If CaCO3 actually accounts for most of the alkalinity, hardness in CaCO3 is equal to alkalinity. Since hard water contains metal carbonates (mostly CaCO3) it is high in alkalinity.

Oct 17, 2011. The theoretical relationship between carbonate alkalinity and pH for seawater ( blue) and freshwater (red) equilibrated with the atmosphere (350 ppm carbon dioxide).
