* Water (H₂O): This is the most abundant component, making up roughly 96.5% of saltwater.

* Sodium chloride (NaCl): This is the most common salt found in seawater, accounting for about 85% of the dissolved salts.

* Other salts: While sodium chloride is the dominant salt, saltwater also contains smaller amounts of other salts, including:

* Magnesium chloride (MgCl₂)

* Magnesium sulfate (MgSO₄)

* Calcium sulfate (CaSO₄)

* Potassium chloride (KCl)

* Calcium carbonate (CaCO₃)

* Bromine (Br)

The precise composition of saltwater varies depending on location, depth, and other factors. However, these are the main ingredients that make up this important natural resource.
