Carbonate hardness is an outdated term from drinking water analysis and is defined as part of the earth’s alkali metals that can be precipitated by heating to form carbonates (scale). This is also where the term ”temporary hardness” comes from. Due to the different composition of seawater and drinking water, however, there is neither temporary hardness nor carbonate hardness in seawater analysis, but only the term alkalinity. Alkalinity is therefore equivalent to the simplified notation KH.
