The Correct Term for Salt in Seawater: Dissolved Salts

Seawater contains a mixture of dissolved salts, not just "salt." The primary constituents are sodium chloride (NaCl), magnesium chloride (MgCl₂), calcium sulfate (CaSO₄), and potassium chloride (KCl), among others. Collectively they constitute ~3.5% salinity by weight.
