Measuring Acid Strength: Ka Values of Weak Acids—ChemTopic™ Lab Activity

firewatch

Acids vary greatly in their ability to produce ions when dissolved in water. With the Measuring Acid Strength: Ka Values of Weak Acids—ChemTopic™ Lab Activity, measure the pKa value for ionization of an unknown weak acid by preparing solutions containing equal molar amounts of the weak acid and its conjugate base by “half-neutralization” of the acid. Then measure and use the pH values to calculate the pKa value for the unknown and determine its identity.

Concepts

  • Weak Acid
  • Equilibrium Constant
  • Conjugate Base
  • Neutralization Reaction
