Study Notes
Acid-Base Titration
- Titration is a process used to determine the concentration of an unknown solution using a solution of known concentration (titrant).
- The titrant is added from a burette to a titrand (the unknown solution) in a conical flask until the reaction is complete (end point).
- Titrant: Solution with a known concentration, placed in a burette.
- Titrand: Solution with an unknown concentration, placed in a conical flask.
- Indicator: A substance added to the titrand to identify the endpoint of the reaction by changing colour.
- Equivalence point: Point where moles of titrand are equal to moles of titrant.
- End point: Point at which the indicator changes colour, signifying the completion of the reaction.
Acid-Base Theories
- Arrhenius Theory: Acids produce H+ ions, and bases produce OH- ions in water.
- Bronsted-Lowry Theory: Acids are proton donors, and bases are proton acceptors.
- Lewis Theory: Acids accept electron pairs, and bases donate electron pairs.
Acid-Base Indicators
- Indicators are substances used to determine the endpoint in titrations.
- They change colour depending on the pH of the solution.
- Indicators are weak acids or bases, changing colour when ionized or unionized.
- Ostwald's theory explains how indicators change colour based on their ionization state.
- Quinonoid Theory explains indicators changing colour because of different tautameric forms.
Acid-Base Classification
- Strong acids completely dissociate in solution.
- Weak acids partially dissociate.
- Strong bases completely dissociate.
- Weak bases partially dissociate.
Neutralization Curve
- Neutralization curves show how the pH of a solution changes as a titrant is added.
- These curves are plotted with pH on the y-axis and volume of titrant on the x-axis.
- Curves show characteristic shapes, and the equivalence point is indicated by a sharp change in pH.
- Various types of curves exist relating different acid/base combinations.
