1 287 Chemistry Salin Lectures Page 1 287 Chapter 10: Acid-Base Titrations These titrations are fundamental to following material Strong Acid-Base (or visa versa ) is very easy Weak-Strong (acid/base) really only a few cases…also easy Detection of endpoints Indicators pH electrodes 287 Chemistry Salin Lectures Page 2 Strong Acid / Base Titration Water H + + OH - H 2 O very strong K = 1/K W = 1/10 -14 = 10 14 Equivalence Point (strong acid/base) Moles of H + = moles of OH - pH = 7

287 Chemistry Salin Lectures Page 3 Strong Acid / Base Titration Example: (remember M = moles/L =m/L) 50.00 mL of 0.0200 M KOH titrate with 0.100 M HBr…. how much do we need in mL? moles of OH -= (0.05 L)(0.020 M) = 0.00100 m (Volume HBr)(0.100 M) = 0.00100 m = 0.010 L = 10.0 mL be careful ! (book way) OR solve for (V HBr )(0.100 M) = (50.0 mL )(0.020 M) What if you are using a diprotoic acid like H 2 SO 4 ? 287 Chemistry
