Percent ionization
percent ionization for a weak acid (ha) is determined by the following formula:

percent ionization=[ha] ionized[ha] initial×100%

for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.
a certain weak acid, ha, has a ka value of 7.6×10−7.
