Lecture 4: Major Ions Conservative Elements and Dissolved
We can broadly classify the elements in seawater into 4 groups: conservative elements dissolved gases recycled elements and scavenged elements The conservative elements: These include most of the major ions in seawater and a few other elements and complexes (Li+ Rb+ Cs+ MoO42- and UO2(CO3)34-) |

Is sea water a compound element or mixture? – Easierwithpracticecom
Sillen's ocean model was composed of nine components: HCl H2O and CO2 which represent acid volatiles from inside the earth and KOH CaO SiO2 NaOH MgO and Al(OH)3 which corresponded to the bases of the rocks The ocean was treated as one giant acid-base titration |

COMPOSITION OF SEAWATER
Ocean water is a combination of freshwater and a variety of dissolved substances Salinity is a measure of the amount of dissolved salts in seawater measured in parts per thousand (ppt) To change the salinity of an ocean three different things can occur: evaporation precipitation or freezing |

Seawater - University of Illinois Urbana-Champaign
Seawater is a solution of salts When a mineral such as NaCl dissolves in water the ions separate and are surrounded by water molecules The lone pair electron orbitals on the oxygen of water interact with the electron-poor cations and the anions donate some of their excess electron density to the electron-poor hydrogen atoms of water |

Is seawater a compound or a mixture?
- Seawater is an example of a solution, which is a homogeneous mixture because the property of seawater is the same all throughout the homogeneous mixture. Seawater is a mixture of salts and water. In this mixture, the salts are called the solute, while the water is called the solvent.
Is seawater a solution or a mixture?
- Yes sea water is a solution. A solution is a fluid mixture in which minor constituents are evenly dissolved in a major fluid constituent. If you needed to establish whether water was pure water or sea water the easiest thing that I can think of without using laboratory equipment is simply boil it dry.
What are the components of sea water?
- sea water, major constituents 99.9% of dissolved material in sea water can be accounted for by eleven constituents: Na, Mg, Ca, K, Sr, Cl, SO 4, HCO 3, Br, BO 3, and F, whose relative proportions are almost constant in all oceans regardless of salinity. The pH of sea water is maintained at 8.0–8.4 by a buffering system.
