Molar Refractivity

Molar refractivity, A, is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction, and ... more

Concentration of a substance (first order reaction)

The concentration of a substance at time “t”, of a first-order reaction, depends only on the initial concentration and the properties of the ... more

Boiling point elevation (ebullioscopy)

Colligative properties are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a ... more

Degree of dissociation of a weak electrolyte
