SUMMARY
The discussion focuses on calculating the concentration of formic acid required for 2.85% ionization, given a dissociation constant (Ka) of 1.80E-4. The equation used is X^2 / (0.0285 - X) = 1.8E-4, where X represents the concentration of ionized formic acid. The initial calculation yielded X = 0.00226, leading to a concentration of 0.0262M, which was identified as incorrect. Participants are encouraged to clarify the interpretation of 0.0285X in the context of the problem.
