Calcium, magnesium, iron, manganese, nitrate, nitrite, chloride,
and sodium are some
of the most abundant ions present in water samples. Two methods
(predominant polyvalent cations
and all polyvalent cations) have been used to measure Total
Hardness (TH). Discuss when
a) TH measured using the predominant polyvalent cations = TH
measured using all polyvalent cations
b) TH measured using the predominant polyvalent cations > TH
measured using all polyvalent cations
c) TH measured using the predominant polyvalent cations < TH
measured using all polyvalent cations
