Ionization constant of fecl3
WebPolarizabilities are normally expressed in cgs units of cm 3. Ground-state polarizabilities are in the range of 10 –24 cm 3 = 1 Å 3 and hence are often given in Å 3 units. Theorists tend to use atomic units of a03 where a0 is the Bohr radius. The conversion is α (cm 3) = 0.148184 × 10 -24 × α ( a03 ). WebThe acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution while the base dissociation constant (Kb) is a measure of basicity—the base’s …
