A solution made with 0.137 moles of a triprotic acid (H3A, K1=9.15 × 10-2; Ka2=9.03 × 10-5; K3=1.00×10) dissolved in 162 mL of solution, was titrated with 0.794 M NaOH. Answer the following question about the pH of the solution, during this titration experiment: What is the pH of the solution when you have added 192 mL of NaOH solution? pH after adding 192 mL of NaOH = number (rtol=0.03, atol=1e-08)
