Dissociation constant of hydrochloric acid
Thread Content
I would like to ask, what is the dissociation constant of hydrochloric acid? Where can one find the dissociation constants of general strong electrolytes? Thank you
The concept of dissociation constant applies to weak electrolytes; strong acids and strong bases are completely ionized. Dissociation constant (pK): It is a polarity parameter of a solute that has a certain degree of dissociation in an aqueous solution. The dissociation constant provides a quantitative measure of the acidity or basicity of a molecule; as pKa decreases, the acidity of a proton donor increases ； For proton acceptors, their basicity increases. pK=PH+log electron acceptor/electron donor
Since hydrochloric acid dissociates so easily, what’s the point of using the dissociation constant?
That is, hydrochloric acid is a strong electrolyte, so its dissociation constant doesn’t make sense; generally, when discussing dissociation constants, it is the weak electrolytes that are considered
