Do the following titration and find concentrations of everything in solution. You have a diprotic acid H2B titrated against 0.07 M NaOH. there is 30 mL of H2B and a concentration of 0.1M Ka= 1.0*10-3 and a Ka2= 1.0*10-7? Then find the concentration of each species in solution at 75 mL of base added? Make sure that all assumptions are clearly list for each step.
