An analytical chemist is titrating 222.7 mL of 0.8100 M solution of formic acid (H2 CO2 ) with a 1.100 M of KOH. The pKa of formic acid is 3.74. Calculate the ph of the acid solution after the chemist has added 83.93 mL of the KOH solution to it.

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b
