Ionization of phosphoric acid
WebPre-Lab Questions Phosphoric acid is a triprotic acid (three ionizable hydrogens). The values of its stepwise ionization constants are K. = 7.5 x 10K = 6.2 x 10", and K = 4.2 x … WebPhosphoric acid undergoes three ionizations, hence it has three pK a values (given as 2.0, 6.8 and 12.0 in the question). Phosphoric acid has great biological significance due to its role in DNA/RNA, energy molecules such as ATP, protein phosphorylation, etc; therefore, it is worthwhile to spend a moment examining its ionization reactions.
