The oceans interact with gases in the atmosphere or solid materials in Earth’s crust. A lot of these gases and solids dissolve in the oceans and form aqueous solutions (symbol (aq)). An aqueous solution is a homogeneous mixture of water (solvent) and another substance(s) (solute). Solutions are the perfect reaction medium – in a solution, the particles are individual atoms, ions, or molecules. By putting reactants in solution they can easily come into contact and hence react. In each the trillions of cells in your body, thousands of reactions in aqueous solution are taking place right now allowing you to function.Titrations can be carried out for any of the three reaction types described above. Two reactants are combined in exact stoichiometric proportions. The volume of a solution of known concentration (the titrant) is added to a known volume of solution containing the analyte (the thing you’re interested in). The equivalence point is when the reactants are present in stoichiometric proportions. An indicator is added
