Webb18 juni 2024 · What is considered a strong Ka? In the formulas, A stands for acid and B for base. A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A small Ka value means little of the acid dissociates, so you have a weak acid. The Ka value for most weak acids ranges from 10-2 to 10-14.
