1. The problem statement, all variables and given/known data 2. Relevant equations Henderson-Hasselbalch Equation 3. The attempt at a solution Sorry for the huge picture, but the number says 0.007558 mol. Is my ICE table correct? Equation: 7.42 = 6.85 + log((0.007558-x)/x) (0.007558-x)/x = 3.715 x = 0.00160 mol H+/(0.07483 L + 0.01339 L) = 0.0181 M = [HCl] It says it is incorrect, though.
