WebAnytime we see the lower case p in front of a constant in chemistry, it will usually mean -log of that value. Since we know that Ka is the acid dissociation constant, pKa simply just means -log of the acid dissociation constant value. Acids will usually dissociate according to the following equations, HA + H 2 O ⇆ A – + H 3 O + (The letter ... Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner. For instance, when an acid dissolves in water, a covalent bond between an … See more For reversible dissociations in a chemical equilibrium the dissociation constant Kd is the ratio of dissociated to undissociated compound $${\displaystyle K_{d}=\mathrm {\frac {[A][B]}{[AB]}} }$$ See more The dissociation of salts by solvation in a solution, such as water, means the separation of the anions and cations. The salt can be recovered by evaporation of the solvent.
