It really helps a lot with my homework, even though you have to pay it's worth it and it tells you the steps also. Few of them are enlisted below. For those who need fast solutions, we have the perfect solution for you. \[ HA + H_2O \leftrightharpoons H_3O^+ + A^- \], \[ K_a = \dfrac{[H_3O^+][A^-]}{[HA]} \label{eq3} \]. This operation gives you the dissociation constant Ka: When Ka is large, it means the conjugate ions aren't strong enough to move the reaction in the opposite direction, which indicates a strong acid. pKa is defined as the negative logarithm (-log) of Ka . MedPR said: Yeah. How to Calculate Ka From Ph | Sciencing Ka is the acid dissociation constant while Kpa is simply the negative logarithm of Ka. Therefore to convert pKa to Ka just find 10^ -pKa in the scientific calculator, you will get it. pKa = -log Ka. concentration=. 00:0000:00 An unknown error has occurred Brought to you by eHow The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot.
