Respuesta :

Answer:

4. Sea water is a solution.

Explanation:

The solution is a type of homogenous mixture in which the solute is dissolved homogeneously in the water. Salt is dissolved in the seawater so the seawater is a type of solution. The salinity of the seawater is about 3.5 % that means about 35 grams of salts are dissolved per kilogram of the water. There are many ions or salts that are present in the seawater such as bicarbonate, sodium ins, chloride ions and some other.
