Acids and Bases
Broad Concept: Acids and bases are important in numerous chemical processes that occur around us, from industrial processes to biological ones, from the laboratory to the environment.
|8.1 ||Define Arrhenius' theory of acids and bases in terms of the presence of hydronium and hydroxide ions, and Bronsted's theory of acids and bases in terms of proton donor and acceptor, and relate their concentrations to the pH scale. *|
|8.2 ||Compare and contrast the nature, behavior, concentration and strength of acids and bases.|
a. Acid-base neutralization
b. Degree of dissociation or ionization
c. Electrical conductivity
|8.3 ||Identify a buffer and explain how it works.|
|8.4 ||Explain how indicators are used in titrations and how they are selected.|
|8.5 ||Describe an acid-base titration. Identify when the equivalence point is reached and its significance.|
|8.6 ||Calculate the pH or pOH of aqueous solutions using the hydronium or hydroxide ion concentration.|
