1. Calculate the pH during the titration of 50.00 mL of 0.1000M phosphoric (H₃PO₄; K_a1=7.1x10^-3, K_a2=6.3x10^-8, K_a3=4.2x10^-13) after adding 18.3 mL of 0.1000M NaOH.

All volumes should have a minimum of 2 decimal places.

2.Calculate the pH during the titration of 40.00 mL of 0.1000M propanoic acid (HPr; K_a=1.3x10^-5) after adding 13.13 mL of 0.1000M NaOH.

All volumes should have a minimum of 2 decimal places.
