Suppose that 27.34 mL of standard 0.1021 M NaOH is required to neutralize 25.00 mL of an unknown H2SO4 solution. Calculate the molarity and the normality of the unknown solution.
Lecture 8: Tuesday, September 20, 2016 Chemistry of Solutions Prof.: N. Schoonhoven Topics covered: equilibrium constants for acids and bases, amphoteric substances, auto-ionization of water, the pH scale, the pH of strong acids. Equilibrium constants for acids and bases For eqm involving an acid reacting with water, K . a Acids with K > 1 are strong, and acids with K < 1 are weak. Water isn't written in eqm a a constants for acids or bases. - + K a [A][H O ]3/ [HA] So a strong acid dissociates according to the following general equation: HA + H O ⇌ A - + H O + or HA ⇌ H + + A - 2 (l) (aq) 3 (aq) (aq) (aq) K as of strong acids are too large to measure in H O 2ecause
