Measurements of freezing-point depression with a precision of ± 0-0002° C have been made on aqueous solutions of potassium chloride and the sulphates of copper, zinc, magnesium, calcium, cobalt and nickel. The results for the sulphates have been analyzed using the theory of incomplete dissociation in a manner which makes clear the physical status of the dissociation constants obtained, and the relation between the approaches associated with the names of Bjerrum and Davies. The values of the dissociation constants are compared with those obtained by other methods.
