Web26 feb. 2024 · Taking the positive value (x₁) we can find the percent ionization (eq 3) Hence, the percent ionization of formic acid is 1.22% when the initial concentration is 1.20 M. b) Ci = 0.450 M From equation (2) we have: After solving the above quadratic equation for x, we have: With the positive value we can find the percent ionization (eq 3) WebThe pKa of an acid is exactly the same as the pH HALFWAY to the equivalence point!Then, Ka = 10^-pKa and you're done. Super easy.Thanks Henderson-Hasselbalc...
