Salinity is often estimated by chlorinity because
A) Chlorine is the only major element of sea water
B) Chlorine is in constant ratio to sodium and other major elements
C) Chlorine can be separated from the rest of sea water simply by evaporation
D) Salinity is not estimated by chlorinity but by sodium concentration

Question

Quizplus · Accepted Answer

Chlorinity is often used to estimate salinity because chlorine (in the form of chloride ions) maintains a relatively constant ratio with sodium and other major elements in seawater. This consistent ratio allows for the estimation of the total salinity of seawater based on the measurement of chlorinity.
