What is the percent ionization of a monoprotic weak acid solution that is 0.171 M? The acid-dissociation (or ionization) constant, Ka, of this acid is 2.32×10−11 .

Determining how many protons (H* ions) an acid can donate and a base can accept is an important aspect in acid/base reactions. The lemon and lime juices you will be using in Parts B and C of this experiment contain citric acid, which is a triprotic acid. Knowing that citric acid is a triprotic acid, how will it stoichiometrically react (what ratio, acid:base) with the standardized NaOH solution that will be used as the titrant? O 3:1 O 2:1 O 1:2 O 1:3
