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 WebThe Ka of HPO 4 2− is 4.2 × 10 −13, and its Kb is 1.0 × 10 −14 6.2 × 10 −8 = 1.6 × 10 −7. Because Kb >> Ka, the solution is basic. (d) The NH 4 + ion is acidic (see above discussion) and the F − ion is basic (conjugate base of the weak acid HF). WebApr 1, 2024 · Weak acids and weak bases do not completely ionize in a solution, hence their concentrations are difficult to determine. Typically, the K a and K b values of weak acids and bases range between 10 -1 and 10 -13. Strong acids and strong bases behave differently compared to their weak counterparts. chacha nehru sports scholarship
