PPT-Lecture 2 - Major Ions in Sea Water

Why do we care about the major ions What is the composition of seawater What defines Major Ions What are their concentrations What are their properties Density distributions and controls salinity and temperature. and stuff like that.. A complex ion is the exception to a rule.... It is an ionic compound that has an overall charge.. Complex ions are identified using square brackets. [ ]. Complex Ions. Are soluble.. Irminger.

Water mass transformation in the Iceland Sea. . - the Denmark Strait Overflow Water. the key is that the electrons of each covalent bond are not shared equally between oxygen and hydrogen atoms. . Oxygen pulls electrons much more strongly than does hydrogen. . This sharing of electrons causes the oxygen end of the molecule to have a slight negative charge,. SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. Chapter 4. Reactions in Aqueous Solution. James F. Kirby. Quinnipiac University. Hamden, CT. Solutions.
