Download Chpt 4: Major Ions Of Seawater James Murray (10/02/01) Univ. Washington . [PDF]
Description: Major Ions Major ions are defined as those elements whose concentration is greater than 1 ppm. The main reason this definition is used is because salinity is reported to 0.001 or 1 ppm. Thus, the major ions are those ions that contribute significantly to the salinity. According to this definition there are 11 major ions. At a salinity of S ..

acid. The acid separates into ions, which is called dissociation. What is left after dissociation are negative ions and positive H ions. The H ions combine with water molecules to form hydronium ions (H 3O ). Therefore, an acid compound produces hydronium ions when dissolved in water. The figure shows the dissociation of
charged atoms attract. Positive ions (metals) attract negative ions (nonmetals), forming ionic compounds. Positive ions attract Negative ions Positive ion of 2 Mg 2 attracts F1- Negative ion of 1- Electron Arrows Electron arrows are an easy way to visualize electrons being given or accepted by atoms. is 2, so it will lose 2 electrons.

Nov 02, 2018 · The sticks in this diagram are there to help show the arrangements of the ions. They do not represent the ionic bonds. Ionic bonding is between ions and all their surrounding oppositely charged ions. Each sodium ion in this structure is surrounded and equally attracted by six chloride ions. Ionic bonding is the attraction between all these ions
Chapter 2 Page 8 Strength of acids and bases: Strength of acids and bases depends on the no. of H ions and OH– ions produced respectively. a. Strong acids give rise to more H ions. eg. HCl, H 2 SO 4, HNO 3. b. Weak Acids give less H ions eg. CH 3 COOH, H 2 CO 3 (Carbonic acid) c. Strong bases give rise to more OH– ions. eg. NaOH, KOH, Ca(OH)
