Question:
What is the most common ocean salt?



Replies:
The composition of seawater depends upon location and depth; however, the typical concentration of dissolved ions in (g/kg) is: Cl(-1) 19.35; Na(+1) 10.78; SO4(-2) 2.71; Mg(+2) 1.28; Ca(+2) 0.71; K(+1) 0.40; HCO3(-1) 0.13; Br(-1) 0.07; Sr(+2) 0.01; B(OH)3 0.03. This totals to about 35.20 g/kg of dissolved inorganic matter. Since the ions are all dissolved they are not "paired up" with one another. This total of inorganic salts is referred to in the literature as "salinity".
