WebWeak acids and the acid dissociation constant, K_\text {a} K a. Weak acids are acids that don't completely dissociate in solution. In other words, a weak acid is any acid that is not a strong acid. The strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid. WebIts ionization is shown below. The ionization of acetic acid is incomplete, and so the equation is shown with a double arrow. The extent of ionization of weak acids varies, but is generally less than 10%. Read More: What is photovoltaic process?
