Name some soluble salts found in seawater.

Seawater contains various soluble salts, with sodium chloride (NaCl) being the most abundant. Other soluble salts found in seawater include magnesium chloride (MgCl₂), magnesium sulfate (MgSO₄), calcium chloride (CaCl₂), and potassium chloride (KCl). These salts result from the dissolution of minerals from the Earth’s crust and volcanic activity. Trace amounts of other salts like sodium sulfate (Na₂SO₄), calcium sulfate (CaSO₄), and potassium bromide (KBr) are also present. The composition of seawater can vary, but these salts collectively contribute to the salinity of the oceans and play a crucial role in marine ecosystems.
