WebFeb 9, 2024 · So for a solution made by combining 0.10 mol of pure formic acid HCOOH with sufficient water to make up a volume of 1.0 L, Ca = 0.10 M. However, we know that the concentration of the actual species [HCOOH] will be smaller the 0.10 M because some it ends up as the formate ion HCOO –. However, it will always be the case that the sum WebIn a 0.10- M solution this base is 0.0015% ionized. Determine Ka for hydrogen sulfate ion, HSO − 4. In a 0.10- M solution the acid is 29% ionized.
