Study Notes
Properties of Acids
- Have a sour taste and are corrosive.
- Change color of vegetable dyes.
- React with "active" metals and carbonates to produce CO2.
- React with bases to form ionic salts.
Properties of Bases
- Also referred to as alkali, with a bitter taste and slippery feel.
- Change color of vegetable dyes.
- React with acids to form ionic salts, a process called neutralization.
Strong Acids
- Notable strong acids include hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, sulfuric acid, chloric acid, and perchloric acid.
Conjugate Bases
- An acid becomes a conjugate base by losing 1 H+ ion.
- Common conjugate bases include:
- H2CO3 transforms to HCO3-
- H2S transforms to HS-
- HF transforms to F-
- HSO4- transforms to SO42-
- HCO3- transforms to CO32-
Conjugate Acids
- A base becomes a conjugate acid by gaining 1 H+ ion.
- Example transformations include:
- CO32- converts to HCO3-
- HCO3- converts to H2CO3
- H2O converts to H3O+
Acid-Base Equilibria
- Double-headed arrows signify weak acids or bases, indicating partial dissociation.
- Autoionization occurs when water reacts with itself, producing H3O+ and OH- ions.
Characteristics of Weak Acids
- The majority of weak acids exist primarily in the form of reactants in solution.
Aqueous Solutions
- All aqueous solutions contain both H3O+ and OH- ions.
Ion-Product Constant for Water
- Represented by Kw, which defines the equilibrium constant for water's autoionization.
pH Concept
- pH quantifies the hydrogen ion concentration, expressed as the negative logarithm of [H+].
Buffered Solutions
- Consist of a weak acid and the salt of its conjugate base, or a weak base and the salt of its conjugate acid, used to resist changes in pH.
