It is a mixture of water, salts and oxygen.
It is a mixture. A pure substance contains only one type of substance or one species of any substance or element. Sea water is a mixture of different salts dissolved in water. Thus, it is not a pure substance. Another point is that the different components of sea water can be observed separately.

Salt water is a homogeneous mixture called a solution containing salt and water. Salt is the solute and water is the solvent. It is a mixture because the salt and water are not chemically combined and are not present in definite proportions.
Mainly salts of different kinds.
Absolutely not. A pure substance is a substance that consists of only one species. This is a hypothetical scenario, as the closest thing in a household is probably copper wire. Even distilled water (a great deal purer than sea water) is a mixture of H2O and some ions.
Boil it. The water will evaporate, leaving salt at the bottom of the pot, which did not evaporate and was left behind.
A mix of salt and water.
