WebIn calculating pH by ICE method of 0.015 M CH2FCOOH (Ka CH2FCOOH = 2.6 x10-3), the change in CH2FCOOH can not be neglected because. a. Acid Dissociation constant, Ka, has a negative exponent. b. pH is not within +/- pka unit of pka of CH2FCOOH c. initial CH2FCOOH concentration is less than 0.1 M d. dissociation of [CH2FCOOH] will be more … WebAug 14, 2024 · Because only 4.98 mmol of OH − has been added, the amount of excess H + is 5.00 mmol − 4.98 mmol = 0.02 mmol of H +. B The final volume of the solution is 50.00 mL + 24.90 mL = 74.90 mL, so the final concentration of H + is as follows: [H +] = 0.02 mmol H + 74.90mL = 3 × 10 − 4 M Hence, pH ≈ − log[H +] = − log(3 × 10 − 4) = 3.5
