In this lecture you will learn about Titration, Indicators, and Buffers. Professor Goldwhite starts by teaching you the basic equipment of Titration and Analysis such as the Buret, Pipet, Stopcock, Volumetric Flask, and reviewing concepts such as Molarity. Next you will cover actual Titrations such as Strong Acid-Strong Base Titrations and Weak Acid-Strong Base Titrations. You will also learn about the pH Meter as well as how to choose the appropriate Indicator such as Phenolphthalein or Methyl Orange. Lastly, you will cover Buffers with an investigation of Buffer Regions in Titrations as well as common Practical Buffers.
for titration: pipet, buret, volumetric flask
= MV applies both to mol./L and to mmol/mL
calculations at several points in strong acid/strong base titration
calculations at several points in weak acid/ strong base titration;
and stong acid/weak base titration
at equivalence point in weak acid/strong base titration is basic; in
strong acid /weak base titration is acidic
are weak acids or bases with different colors in neutral and ionic
are most useful at pH close to their pK
solutions resist pH change if diluted, or if small amounts of strong
acids or bases are added; useful in chemical and biochemical work
solutions are made from weak acids and their salts; or weak bases
and their salts
