[02-Jan-2019] Seawater is a mixture of many substances, the most abundant of which is water. Water, H2O, is the solvent in the mixture of seawater. The properties of water determine many of the properties of seawater. The solutes in seawater, including dissolved salts, gases, and other substances, also contribute to the properties of seawater. Concentration is the amount of solute or solutes dissolved in a mixture. The concentration of dissolved substances in seawater affects the properties of seawater. In this activity, students will determine how the amount of dissolved substances in solutions (i.e., concentration) is expressed and how concentration affects a solution.
