Which of the following describes the relationship between acid strength and ka value for weak acids?
Leona [35]
I think the correct answer would be when ka increases, the acid strength increases. Ka is the product of hydronium ions and the [A-] ions  concentration over the acid concentration. Therefore, increasing the the Ka, the numerator in the definition would increase as well which correspondingly increase the strength of the acid.
