Web2 days ago · The value of the acid dissociation constant is the reflection of the strength of an acid. The higher value of Ka indicates the higher strength of the acid. The reaction equations along with their Ka values are given below: H2CO3 (aq) <=====> HCO3- + H+ Ka1 = 4.3 X 10−7 mol/L; pKa1 = 6.36 at 25°C WebMar 26, 2024 · Kb for CH₃COO⁻ is 5.6 × 10⁻¹⁰ and the Kb for ClO⁻ is 3.3 × 10⁻⁷. (a) Given that Ka for acetic acid is 1.8 × 10⁻⁵ and that for hypochlorous acid is 3.0 × 10⁻⁸, which is the stronger acid? The acid ionization constant ( Ka) is a way to measure the strength of an acid. The larger the Ka, the stronger the acid.
