The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the substance is always the same.

In this article, you will learn about the meaning of seawater, origin, composition, and impacts, etc. Seawater, or saltwater, is sea or ocean water. On average, seawater in the oceans of the world has a salinity of about 3.5 percent. This means that every kg of seawater contains approximately 35 grams of dissolved salt.
