Problem

A certain weak acid, HA, has a Ka value of 6.7 X 10 -7.

Calculate the percent ionization of HA in a 0.10 M solution. Express your answer to two significant figures and include the appropriate units.

 

Solution
  • Percent ionization is equal to the concentration of H+ divided by the concentration of the acid then multiplied by 100%

  • Concentration of H+ can be calculated by setting up an ICE table
