Chapter 14 Outline
* 14.1 The Nature of Acid and Bases
* Acid-Base Theories
* Arrhenius- Acid is a hydrogen producer and a base is a hydroxide producer * Bronsted-Lowry- Acid is a proton donor and a base a proton acceptor * Lewis- An acid is an electron pair acceptor, and I base is an electron pair donor * Conjugate base & acids

* Ka= [products]/[reactants]
* Acid dissociation constant
* 14.2 Acid Strength
* In a strong acid dissociate almost 100%
* Ka is large
* Strong acid yields weak conjugate base
* Weak Acid
* Does not dissociate much
* The weaker the acid, the stronger conjugate base
* H2SO4(aq)--->H+(aq) +H SO4-
* Oxyacid
* Acidic proton attached to an oxygen atom
* Amphoteric
* Water is the most amphoteric substance
* Kw- 1.0 x 10^-14
* 14.3 The pH scale
* pH scale
* Provides a convenient way to represent solution acidity * The number of decimal places is equal to the number of sig figs in the original number * pH decreases as [H+] increases

* pH + pOH= 14
* 14.4 Calculating the Ph of a Strong Acid Solution
* Major species
* HCl major species are H+ Cl- H20
* 14.5 Calculation the pH of a weak acid
* Always write the major species first
* THE WEAK EAT RICE
* Reaction
Initial
Change
Equilibrium
* Validate
* [x]/[initial concentration] X 100
* It HAS to be less than 5%
* The equation of validity is the same as percent dissociation * 14.6 Bases
* Strong Bases
* LiOH
* NaOH
* KOH
* Ca(OH)2 Slaked lime
* Sr(OH)2
* Ba(OH)2
* Weak bases… everything else with an OH-
* Amines
* Methylamine- CH3
* Dimethylamine-(CH3)2NH
*...
