SpletThe lower the pKa, stronger is the acid strength whereas when pKa is higher, acid strength is weaker. The pKa values of less than zero are considered very strong acids, while the pKa values in between 0 and 9 are generally considered as weak acids. SpletThe acidity and pKa values depend on the stability of a conjugate base.

Splet05. sep. 2024 · 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. The pKa gives the same information, just in a different way. The smaller the value of pKa, the stronger the acid. Weak acids have a pKa ranging from 2-14.

SpletKa = [A – ] [H + ]/ [HA] The reaction and definition can then be written in a more straightforward manner. pKa = – log10Ka. It is more convenient to discuss the logarithmic constant, pKa, for many practical uses.
