The phthalic acid is a diprotic acid (pKa1-2.95, pK₂2-5.41). A titration sample was prepared by dissolving 2.23 g of C6H4(CO₂H)2 in enough water to make 0.120 L. The solution was titrated with 1.552 M NaOH. Calculate the pH at the following points: 1. Before the titration. i eTextbook and Media 2. The 1st midpoint. i 3. The 1st stoichiometric point.

A chemist titrates 60.0 mL of a 0.7169M lidocaine (C14H2|NONH) solution with 0.4965 M HNO, solution at 25 °C. Calculate the pH at equivalence. The p Kb of lidocaine is 7.94. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HNO, solution added. pH %3D
If 40.0 mL of formic acid with a concentration of 0.300 M and a Ka of (2.258x10^-5) is titrated with 0.300 M lithium hydroxide what is the pH of the solution after 20.00 ml of base has been added? Note: Your answer is assumed to be reduced to the highest power possible.

Reaction: NaHCO3(aq) + HCl(aq) ® NaCl(aq) + CO2(g) + H2O(l) Methyl orange is a pH indicator. It is yellow above pH 4.4, orange between pH 4.4 and 3.2 and red below pH 3.2. NaHCO3 is a weak base and it must be acidified to about pH 4 to completely neutralize it. Why did you test the reaction mixture with this indicator before you began the evaporation step?
