In reactions involving coordination compounds, the metal acts as the Lewis acid (electron-pair acceptor), while the ligand acts as a Lewis base (electron-pair donor) In the reaction above, the ammonia ligand displaced the water ligand from the chromium complex because nitrogen is a better electron-pair donor (less electronegative) than oxygen The nitrogen in the ammonia and the oxygen in the water are the donor atoms They are the atoms that actually donate the electrons to the Lewis acid The coordination number is the number of donor atoms that surround the central atom As seen above, the coordination number for Cr3+ is 6 Coordination numbers are usually 2, 4 or 6, but other values can be possible Silver (Ag+) commonly forms complexes with a coordination number of 2; zinc (Zn2+), copper (Cu2+), nickel (Ni2+ ), and platinum (Pt2+) commonly form complexes with a coordination number of 4; most other central ions have a coordination number of 6 + AgCl( s) + 2 NH3 (aq ) Ag(NH3 )2 (aq ) + Cl (aq ) Zn(OH)2 ( s) + 2 OH (aq ) Zn(OH)4 (aq ) Fe 3+ (aq ) + 6 CN (aq ) Fe(CN)6 (aq )

Acids and bases are extremely common, as are the reactions between acids and bases The driving force is often the hydronium ion reacting with the hydroxide ion to form water The chapter on Equilibrium describes the equilibrium reactions of acids and bases, as well as some information concerning acid base titration After you finish this section, you may want to review the acid base part of the Equilibrium chapter

At the macroscopic level, acids taste sour, may be damaging to the skin, and react with bases to yield salts Bases taste bitter, feel slippery, and react with acids to form salts + At the microscopic level, acids are defined as proton (H ) donors (Br nsted Lowry + theory) or electron-pair acceptors (Lewis theory) Bases are defined as proton (H ) acceptors (Br nsted Lowry theory) or electron-pair donors (Lewis theory) Consider the gas-phase reaction between hydrogen chloride and ammonia: HCl( g )+ :NH3 ( g ) HNH3 + Cl (or NH4+ Cl )

+ + HCl is the acid, because it is donating an H and the H will accept an electron pair + from ammonia Ammonia is the base, accepting the H and furnishing an electron pair that + the H will bond with via coordinate covalent bonding Coordinate covalent bonds are covalent bonds in which one of the atoms furnishes both of the electrons for the bond After the bond is formed, it is identical to a covalent bond formed by donation of one electron by both of the bonding atoms Acids and bases may be strong, dissociating completely, or weak, partially dissociating and forming an equilibrium system(See 15 for the details on weak acids and bases) Strong acids include:

1 Alkali metal (Group IA) hydroxides (LiOH, NaOH, KOH, RbOH, CsOH) 2 Ca(OH)2, Sr(OH)2, and Ba(OH)2 The strong bases listed above are all compounds that dissociate completely, yielding the hydroxide ion (which is really the base, not the compound) Unless told otherwise, assume that acids and bases not on the lists above are weak and will establish an equilibrium system when placed into water Some salts have acid base properties For example, ammonium chloride, NH4Cl, when dissolved in water will dissociate and the ammonium ion will act as a weak acid, donating a proton We will examine these acid base properties in more detail in the next section Certain oxides can have acidic or basic properties These properties often become evident when the oxides are dissolved in water In most case, reactions of this type are not redox reactions Many oxides of metals that have a +1 or +2 charge are called basic oxides (basic anhydrides), because they will react with acids Fe 2O3 ( s) + 6 HCl(aq ) 2 FeCl 3 (aq ) + 3 H2O( l ) Fe 2O3 ( s) + 6 H + (aq ) 2 Fe 3+ (aq ) + 3 H 2O(l ) Many times they react with water to form a basic solution: Na 2O( s) + H2O( l ) 2 NaOH(aq ) Na 2O(s) + H 2O(l ) 2 Na + (aq ) + 2 OH (aq ) Many nonmetal oxides are called acidic oxides (acidic anhydrides), because they react with water to form an acidic solution: CO2 ( g ) + H 2O(l ) H 2CO3 (aq ) H2CO3(aq) is named carbonic acid and is the reason that most carbonated beverages are slightly acidic It is also the reason that soft drinks have fizz, because carbonic acid will decompose to form carbon dioxide and water
