1) A cetain weak acid, HA, has a Ka value of 1.4E-7 A) Calculate the percent ionization of HA in a 0.10 M solution. B) Calculate the percent ionization of HA in a 0.010 M solution. 2) A particular sample of vinegar has a PH of 3.20: If acetic acid is the only acid that vinegar contains (Ka=1.8E-5) , calculate the concentration of acetic acid (HC2H3O2) in the vinegar.
