<p>Water is seldom pure. Because of the structure of the <a data-lesson="unique-properties-of-water" data-subject="chemistry" data-tutorial="states-of-matter" href="https://app.ulearngo.com/chemistry/states-of-matter/unique-properties-of-water">water</a> molecule, substances can dissolve easily in it. This is very important because if water wasn't able to do this, life would not be possible on Earth.</p>
<p>In rivers and the oceans for example, dissolved <a data-lesson="occurrence-preparation-and-compounds-of-oxygen" data-subject="chemistry" data-tutorial="metals-metalloids-nonmetals" href="https://app.ulearngo.com/chemistry/metals-metalloids-nonmetals/occurrence-preparation-and-compounds-of-oxygen">oxygen</a> means that <a data-lesson="nitrogen-fixation" data-subject="chemistry" data-tutorial="metals-metalloids-nonmetals" href="https://app.ulearngo.com/chemistry/metals-metalloids-nonmetals/nitrogen-fixation">organisms</a> (such as fish) are able to respire (breathe).</p>
<p>For plants, dissolved <a data-lesson="the-importance-of-nutrients" data-subject="chemistry" data-tutorial="chemistry-real-world" href="https://app.ulearngo.com/chemistry/chemistry-real-world/the-importance-of-nutrients">nutrients</a> are available in a form which they can absorb. In the human body, water is able to carry dissolved substances from one part of the body to another.</p>

Ions in Aqueous Solution

Chemistry generally explores the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances. 

Chemistry

Explore how different substances dissolve and react with each other in water, including ionization and conductivity, precipitation reactions, tests for anions, and various types of reactions such as redox and ion exchange.
