5. a) Determine the ratio of deprotonated(OBr-)/protonated(HOBr) form of hypobromous acid, and the fraction of each, at a pH of 7.5 using the long method (not ionization fraction table); pKa in Table 4.1. b) Repeat using the ionization fraction table. C) If the total concentration of hyprobromous acid (HOBr+OBr- ) is 2 mM, calculate the concentration of each species in mM. 6. If pH = 8.5, what fraction of hypochlorous acid is protonated, and what fraction is deprotonated? Show steps (i.e. value for ).
