Seawater is a mixture. It is a combination of salt and water that is a homogeneous mixture. An example of a pure substance is either pure salt or pure sugar.
A solution.
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.
Seawater is a mixture - a compound is a chemically bonded substance involving more than one element.
Rock salt contains all the minerals found in the seawater from which it formed. These will be many, but NaCl will be the main one.

Pure quartz sand and salt is are pure substances (single chemical compounds), Seawater is a mixture of substances.
seawater is a homogeneous mixture. The water being the solvent and the salt being the solute. A heterogeneous mixture is mixed but not as thoroughly as a homogeneous mixture. None of these though are chemically combined, none are compounds. (hence mixture)
It is an impure substance. It contains a mixture of water, salt and other elements found in the sea. Using seawater can produce incorrect results as elements in seawater can react with other things.
Seawater may be considered a heterogeneous mixture because contain many insoluble materials.
no, a homogeneous mixture is salt water, seawater has other particles in it like sand, bacteria, and other debris that can be seen making it heterogeneous
It is a mixture because there are still multiple small elements left in it, for example minerals like chalk cannot be filtered but do not affect the taste etc By alex, 12
