b) Phosphoric acid: pH4 H2PO4- / pH8 HPO4 2- / pH 11 HPO4 2- 10. Calculate the pH of a 1 L solution containing *pH= -log [H+] [H+]= Kw/[OH-] Kw (a constant)= 10^-14 M^2 a) 10 mL of 5 M NaOH (0.010 L)(5 mol*L^-1 NaOH)/(1L)= 0.05 M NaOh or 0.05 OH- [H+]= (10^-14)/(0.05) =2*10^-13 M pH= -log(2*10^-13 M) = 12.7
